Answer explanation

Do you remember that we said that if we multiply terms with different bases and the same exponent, we multiply the bases and keep the exponent same?

Well, a similar rule applies when we are talking about dividing. We still keep the exponent the same; it's just that we divide the bases instead of multiply.

Which of the following pairs of exponents would make this equation true?

• 5 and -2

• 3 and 1

• 6 and 2

• 5 and 2
