How do you find the cube root of a negative number?
If the negative number is "-a", then you can say the cube root is "-(cube root of a)" Because if you cube a negative number, you get a negative number. So if you cube root a negative number, you get a negative number. Ex) cube root of -8 = -2 Because (-2)^3 = -8 But if you want to find the complex cube roots, you can make an equation: "x^3=-a" or "x^3+a=0" We know one of the roots is "-(cube root of a)" so you can factor the equation by (x+(cube root of a)) And then you use the quadratic formula for the quadratic equation you're left with. Ex) x^3=-8 or x^3+8=0 Since -2 is a root, factor it by (x+2) x^3+8=(x+2)(x^2-2x+4) Using the quadratic formula, you get "1+i√3" and "1-i√3" Therefore the three cube roots of -8 is <"-2", "1+i√3", "1-i√3">
How Do You Find Integer On Math Problems?
An integer is any whole number. It could be positive, zero or negative.
The sum of the squares of two consecutive negative even integers is 100 find the integers?
The negative part is just a trick because any number squared, whether positive or negative, will turn out to be a positive number. But, to satisfy the question... -6*-6=36 -8*-8=64 36+64=100 tada. -6 and -8 would be the answer.
How do you find a negative slope intercept of a vertical line?
A vertical line does not have a slope - negative or positive. It is not defined. A vertical line has no y intercept and, if its equation is x = c (for some number c), then the x-intercept is (c, 0).
When negative five is subtracted from a number the result is 10 Find the number?
The number is 5.
How do you find the cube of a negative number?
The cube of a negative number is negative. Negative times negative is positive, but then you have the third multiplication, and positive times negative is negative. So for example (-2)3 = -8.
Why is it possible to find a real cube root of a negative number but not a real square root of a negative number?
You cannot get real square root of a negative number because two numbers multiplied by themselves are always positive You can always get a real cube root of a negative number because three negative numbers multiplied by themselves give a negative .
How do you find difference a negative number and a positive number?
to find the difference between a negative number and a positive number, you do the same thing as you would do for a positive and positive number. You just subtract the smaller number (which would of course be the negative) from the larger number (the positive). example: difference between 7 and -4 7 - (-4) = 11
What is a negative times a positive times a positive?
A negative. If you have a string of positive and negative numbers multiplied together, all you need to find the sign of the answer is to find the parity of the negative numbers. If there are an odd number of negatives then the answer is negative and if there are an even number of negatives then the answer is positive. Remember, positive numbers make no difference to the sign of the answer.
What number goes into 750?
The following are factors of 750, meaning they go into 750 a certain number of times. To find out how many times the number goes into 750, find the corresponding number on the other side of the array. For instance to see how many times 5 goes into 750, find the 4th-last number in the array (150):1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
How do you divide a negative number by another negative number?
a negative number divided by a negative number is a positive number. This chart can be used to find the quotient or product when dividing and multiplying integers PNN NPN NNP for example, P P P means that a positive multiplied or divided by a positive = a positive.
Why isn't it possible to take the square root of a negative number while you can find the cube root?
think about it this way... a negative times a negative is a positive... squaring is the same as multiplying it by itself. 4^2 is 16, 4X4 is 16. -7X-7 is positive 49. So a square can't be negative, therefore a negative cannot be square rooted.
How do you find absolute value of positive and negative numbers?
To find the absolute value of a positive number all the answer is is the number in between the lines. For example, the absolute value of [340] is 340. To find the absolute value of a negative number, it is simply the opposite (positive version) of the negative number. For example, the absolute value of [-56] is just 56.
How do you find the answer 410 17divided-19?
If the question is 41017 ÷ -19 then the answer is -2158.79 (2dp) If the question is 410.17 ÷ -19 then the answer is -21.5879 (4dp) When dividing a positive number by a negative number then the answer will be negative. Also, when a negative number is divided by a positive number the answer is a negative number.
Explain how you can find the sign of the product of two or more rational numbers?
Negative times negative equals positive. Positive times positive equals positive. Positive times negative equals negative. If you have more than two numbers, multiply the first two and then apply these rules to each successive number in turn.
Can you cube root negative two?
yes, you can find a real root to the cube root of any negative real number. There will also be two complex roots which satisfy it, as well.
How do you find the absolute the Absolute Value?
The absolute value of a number is the positive (or non-negative) value of the number. The absolute value of 0 or a positive number is the number itself. The absolute value of a negative number is its positive equivalent.
