What is the same as?

Possible Answers:     Correct answer: Explanation:

While a positive exponent says how many times to multiply by a number, a negative exponent says how many times to divide by the number.

To solve for negative exponents, just calculate the reciprocal. ### Example Question #9 : Negative Exponents

Solve: Possible Answers:     Correct answer: Explanation:

To evaluate a negative exponent, convert the exponent to positive by taking the inverse. ### Example Question #10 : Negative Exponents

Simplify: Possible Answers:     Correct answer: Explanation:

To simplify this expression, first make all of the negative exponents positive. That means putting them in the opposite position (if they're in the numerator, put it in the denominator and vice versa).

It should then look like: .

Then, combine like terms. Remember, if bases are the same, add exponents!

Therefore, your answer is: ← Previous 1 3 4 5 6 7 8 9 76 77
