Exponents Product, Power Rule

Simplify the following expression:

(-4r⁵)(2r⁸)

• -8r¹³

• -2r¹³

• -8r⁴⁰

• -2y⁴⁰

Simplify the following expression:

(3x⁴y⁵)²

• 9x⁸y¹⁰

• 6x⁸y¹⁰

• 3x⁸y¹⁰

• x⁸y¹⁰

(3⁴)(3⁷)

• 3²⁸

• 3³

• 3^-3

• 3¹¹

Billy was asked to solve 3⁵∙3⁴. He got 9²⁰. What error did he make?

• When he multiplies exponents, he is supposed to add the base and the exponent

• When he multiplies exponents, he is supposed to multiply the base and keep the exponents

• When he multiplies exponents, he is supposed to keep the base and add the exponents if the base is the same

• None of the above

Using exponents, simplify the following expression:

5⁵ * 5^-3

• 5^-15

• 5⁸

• 5^-8

• 5²

(5³)⁷

• 5²¹

• 5¹⁰

• 5⁴

• 125²¹

Anything raised to a power of zero is always: 

• 0

• 1

• itself

• negative

Which is the expanded form of 
5³

• 3 x 3 x 3

• 5 x 5

• 5 x 5 x 5

• 5 x 3
