How do you change negative exponets to positive exponents?

A negative exponent of a number is the same as the reciprocal of that same number to the equivalent positive exponent.EXAMPLE : 2-3 = 1/23When multiplying powers of the same base the rule is, addthe exponents.So, if the initial exponent is negative then the number has to be multiplied by a power of that number with an equivalent positive exponent greater than the negative exponent.EXAMPLE : 2-3 x 25 = 2(-3+5) = 22 (As 5 > l3l then the resultant exponent is positive)

What is all the power and exponents 1-10?

All the powers and exponents of 1 are 1.The powers and exponents of any of the other numbers up to 10 are equivalent to the all the positive numbers - rational and irrational.

How do you get the negative of 4 to the 7th power?

Negative numbers to even powers will be positive, negative numbers to odd powers will be negative. The answer is -16,384.

How do you change negative powers to positive?

You take away the negative sign and put 1 over the base with the (now positive) exponent. Example: x to the negative 2 becomes 1 over x to the 2nd.

What are the seven rules for exponents?

Rules for exponents to multiply powers, add the exponents to divide powers, subtract the exponents to find a power of a power, multiply the exponents to find a power of a quotient, apply the power top and bottom to find a power pf a product, apply the exponent to each factor in the product x0 = 1 anything to the power zero equals one x-a = 1/xa a negative exponent means "one over" the positive exponent

What do you with two negative exponents when multiplying?

I presume you mean you are multiplying two powers of the same base, where both exponents are negative. Regardless of the signs of the exponents, you algebraically add the exponents. For example, 2-3 times 2-4 is 2-7; 35 times 3-8 is 3-3.

Is it true if a negative number is raised to the 18th power the answer will be negative?

No. Negative numbers to even powers are positive.

How are exponents and powers different?

They are not. Exponents, powers and indices are terms used for the same thing.

What are the powers of 10?

10, 100, 1000, 10000, ... are the positive powers. 0.1, 0.01, 0.001, ... are negative powers.

What is 4 to the power -2?


When a negative exponent has no meanig but is introduced to complete the set of exponents?

It certainly has a meaning. It is only meaningless if you consider powers as repeated multiplication; but the "extended" definition, for negative and fractional exponents, makes a lot of sense, and it is regularly used in math and science.

How do you turn algebra with negative powers into fractions?

A negative powers is defined as the reciprocal of the corresponding positive power. For example, 10-3 is the same a 1 / 103.

Why do you use exponents?

Exponents are used in many different contexts and for different, though related, reasons. Exponents are used in scientific notation to represent very large and very small numbers. The main purpose it to strip the number of unnecessary detail and to reduce the risk of errors. Exponents are used in algebra and calculus to deal with exponential or power functions. Many laws in physics, for example, involve powers (positive, negative or fractional) of basic measures. Calculations based on these laws are simper if exponents are used.

Is a negative to a negative power positive?

No, or more accurately "not necessarily".A negative to any even power is positive. -2, -4, -6 etc. are even, so a negative number raised to any of those powers will be positive.However, a negative number raised to an odd negative power (-1, -3, -5 etc.) will be negative.

What does it mean to multiply two powers having the same base and add the exponents?

This is one of the laws of exponents, which states that xa * xb = x(a+b) The base is x, and the two powers (or exponents) are a and b.

How do use the quotient of powers property to simpilfy an expression leaving no negative exponents?

Oh I hate these! I have quiz tomorrow on them, which stinks. Im in pre-algebra though

When do add exponents?

when you multiply powers with the same base.

Positive and negative of the leadership by Stalin?

the positive was that he basically won the WOrld War II for the allied powers. The battle of Stalingrad was the reason Germans had to surrender

How do you prove that a to the power of 0 equals 1?

You first define negative powers as the reciprocals of the positive powers ie x-a = 1/xa. You have the folowing property for positive powers: xa * xb = xa+b You extend the following property to negative powers: So xa * x-a = x0. But by definition, xa * x-a = xa * 1/xa = 1 So x0 = 1

How do you solve negative powers?

The easiest way to solve negative powers is by writing it all out.You already know that positive powers (regular exponents) turn from something like 33 to 3 X 3 X 3 to equal 9 X 3, or 27.Essentially, negative powers works in a very similar manner.2-5 works out to this in expanded form: -2 X -2 X -2 X -2 X -2.It is best to start by multiplying that expanded form in pairs. So, you group -2 X -2, and then -2 X -2, and leave the last -2 for later. -2 X -2 is a positive 4 for both results. Now, multiply both of the 4s to get 16. Now multiply that by the remaining -2 to get -32.Tip: A shortcut method for doing this is recognizing that if the negative exponent is odd, then the answer will be multiplied just like a regular positive exponent, but the answer will be negative, and that if the negative exponent is an even number, the answer will be just like a regular positive exponent and the result will be a positive number.Ex: 2-3 = -8 , while 3-2 = 9.
