Combining the exponent rules

Combining the exponent rules

We have now learned all individual exponent rules in the previous sessions. In this session, we will try to use different exponent rules to solve problems.

Lessons

• 1.
What are exponent rules?

• 2.
Simplify the following and write the answer with positive exponents
a)
$(\frac{(-16a^5b^{-3}) (3a^3b^5)}{2a^2b^{-2}} {)^3}$

b)
$( \frac{(x^{3y+5}) (x^{4y-2})}{x^{y+3}} )$

c)
$(-3{x^5}{y^4}{z^9}{)^{-3}} (-5 {x^4}{y^{-3}}{z^{11}}{)^4}$
