multiplying and dividing exponents

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

• add
• subtract
• multiply
• divide

8⁷ ⁄ 8²

• 8⁵
• 8⁹
• 8¹⁴
• 1⁵

x⁵⁄x³

• x²
• x
• 1
• x⁸

x⁴ (x¹²)

• x³
• x⁴⁸
• x¹⁶
• x⁸

3⁴ ⋅ 3⁷

• 3²⁸

• 3³

• 3^-3

• 3¹¹

 $\frac{n^8}{n^4}$  

•  $n^{4\ }$  

•  $n^{12}$  

•  $n^{-4}$  

•  $n^{-12}$  

Simplify:  $\frac{9h^6}{3h^3}$  

•  $3h^9$  

•  $3h^{3\ }$  

•  $3h^{18}$  

•  $h^{3\ }$  

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

Simplify: $\left(5a^3b^5\right)\left(-8ab\right)$  

•  $-40a^4b^6$  

•  $-40a^3b^5$  

•  $-40a^2b^4$  

•  $-3ab$  

Simplify: $\left(5x^3\right)\left(-3x^5\right)$  

•  $-15x8$  

•  $2x^8$  

•  $-15x^2$  

•  $-15x^{-2\ }$
