Is the number positive if the power is negative?

It does not work that way. A negative power is simply the reciprocal. So that x-a = 1/xa The reciprocal is negative or positive according to whether the number itself is negative or positive. [And, if the number is 0, the reciprocal is not defined.]

How do you figure out negative 24 multyplied by the fraction two thirds?

Consider that you have a negative times a positive, so the final result will be negative.Work out 24 x 2/3 and make sure the result is negative.When multiplying numbers, there are 2 different cases to think about with regard to the signs of the numbers:If the signs of the numbers are the same (positive and positive, or negative and negative) then the result will be positive;Otherwise if the signs are different (that is if one number is positive and the other is negative) the result will be negative.

Is the cube root of negative number a positive?

No, because the inverse function would not work. Every time you multiply a positive by a positive you get a positive.

How do you determine negatives or positives in math equations?

Numbers are justified as positive, which is usually written as just a number but can be written with a plus (+) sign in front of the number. (e.g. 15 or +15), or negative. Negative numbers are numbers in the negative integers, or below 0. They are written with a minus (-) sign in front of them. (e.g. -15) ---------------------------------------------------------------------------------- ..::To solve remember these rules::.. When multiplying: positive x negative = negative positive x positive = positive negative x negative = positive When dividing: positive / negative = negative positive / positive = positive negative / negative = positive When adding: In a positive + negative situation, if the negative number has a higher number than the positive (e.g. -25 + 10) then the number is negative, this is always true when adding a higher negative to a positive. If the positive has a higher number (e.g. 25 + -10) then it's just the opposite, it will be a positive number. -------------You can solve these very easily: 25 + -10 --> (25) + (-10) to keep it well organized and easier to work with,now just remember "Keep Change Change"... - keep 25 as it is, change "+" to a "-" and change the "-10" to a positive 10. As a result, you will have: 25 - 10. Now solve. Answer = 15 (positive). If for instance you have a negative + positive, the same rules apply (Keep Change Change) negative + negative = negative positive + positive = positive When subtracting: negative - positive (vice versa), use Keep Change Change as you did with adding positives and negatives. negative - negative, use Keep Change Change positive - positive, use Keep Change Change if the number you are subtracting is a higher number. (e.g. 10-15) If you need anymore help, try asking a more specific question again on Wikianswers, search for math websites on the web, or ask your teacher or college professor for help.

What is 7 plus two-thirds times equals negative one?

well first of all if I gave you the answer it would be cheating. but I will show you a better way to do the problem. seven plus two thirds is easy. It is seven and two thirds. now times that by negative one . remember your integer rules. Positive times a positive is equal to positive. negative times positive is negative is but a negative times a negative is a positive. b so seven and two thirds times negative one is negative seven and one thirds. I hope that I could have been of some assistance to your problem. Remember to work the problem one step at a time. If you look at the whole problem you will get confused. look at segments than put it all together. good luck.

When do you say that the work done is positive or negative?

There are different conventions as to what work is negative and what work is positive. The convention used by engineers and physicists is that work done BY the system on its surroundings is positive while work done ON the system by its surroundings is negative. Chemists reverse these conventions.

How do you work out how to divide a positive number by a negative number?

Pretend the negative number is positivedivide the positive number by a positive numbermake the result negative.For example, divide 12 by -6:Pretend -6 is 6divide 12 by 6 to get 2make the result negative to give -2Thus 12 ÷ -6 = -2

Does air friction do positive negative or zero work on your car when you are coasting?

negative work

If a process is carried out at constant pressure P and the volume V of the system decreases then V is negative positive and the work w is negative positive zero?

In this case, V would be negative, and work w would be positive.

How do you determine a work done is positive sign or negative sign?

If work is done on the system then it has a negative sign. If work is done by the system then it has a positive sign.

Is a negative a positive is what?

A Negative plus a positive = a negative because negative and a positive cannot work together Negative + Negative= Positive Positive + Positive = Positive when your dealing with numbers such as : -2 + 2 would equal a negative 4 -2 +-2 would equal a positive 4

How does it work when a negative number is divided by another negative number?

you divide regularly but since both numbers are negatives the answer is positive example -5 divided by -9 equals 45

How would you Explain how you would decide whether the product of three numbers is positive or negative?

If all three numbers are positive then the product obviously has to be positive. If TWO of the three numbers are negative, then the product is also positive. But if exactly ONE of the three numbers is negative or if all THREE are negative, then the product must be negative. In general, a product of numbers is negative if an ODD NUMBER of the terms is negative.

Why is it that multiplying two negative integers gives a positive result but multiplying two positive integers cannot give a negative result?

It is well known that if you multiply a positive number (it doesn't have to be an integer) by another positive number the result is always a positive number. For example (+2.3) x (+2) = +4.6 Similarly, at school you learn that if you multiply a positive number by a negative number the result is always a negative number. For example (+19) x (-2) = -38 When you multiply two negative numbers you must get a positive result because of the way negative numbers "work", but why that is so is not usually explained at junior or high school. You learn why as part of learning about complex numbers in higher math at technical college or university. To be very brief, it is all to do with the behaviour of the operator "i". (For more information about it please see the answer to the related question shown below.) Because i2 is defined to be equal to -1 then it follows that i2 x i2 = +1 for the following reason: multiplying something by i2 means "apply the operator i twice" so, if you start with a positive number, multiplying it by i2 makes that positive number into a negative number. If you multiply that negative number by i2 again you make the result into a positive number. Overall you are applying the operator i four times so you can say that i2 x i2 (which is the same as i4) means "apply the operator i four times" and doing that gives a result which is a positive number. For example (-1) x (-2) = +2 could be written as: [(+1) x i2] x [(+2) x i2] = +2 x [(i2 x i2)] = +2 or even as (+1) x i2 x (+2) x i2 = +2 x i4 = +2
