Multiplying and Dividing with Exponents Practice

• y²⁰
• y³
• y²⁶
• 3y

• 2¹⁴ z¹³
• 2²/z⁷
• 2¹⁴/ z⁷
• 2² z⁷

According to exponent rules, when we multiply two power with the same base we _______ the exponents.
Example: c⁶ ⋅ c⁴

• add

• subtract

• multiply

• divide

When multiplying exponential expressions with the same base, what always happens to the exponents?

• they are added together

• they are subtracted

• they are divided

• they are multiplied

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

• 8x⁴
• 8x⁸
• 6x⁴
• 6x⁸

What is the base and exponent of this power: 4^-6

• Base: 4, Exponent: 6

• Base: 6, Exponent: -4

• Base: 4, Exponent: -6

• Base: -6, Exponent: 4

Use the quotient rule to simplify the monomial.

• ab

• a⁸b⁷

• a⁴b¹

• ab31

Multiply. Give the product in scientific notation. (9.6×10³) × (6.7×10²)

• 6.432×10⁵

• 6.432×10⁶

• 6.432×10¹

Divide. Give the quotient in scientific notation.

(3 x 10^-5)/(4 x 10²)

• 7.5 x 10^-3

• 7.5 x 10^-8

• .75 x 10^-7

•  7.0 x 10²
