Question

Please simplify the following with steps plss

Answer 1

Answer:

Lets solve each group separately...

Question 1:

STEP ONE:

$\frac{1}{5}^{45} * \frac{1}{5}^{-60} = \frac{1}{5}^{45+(-60)} = \frac{1}{5}^{-15}$

STEP TWO:

$\frac{1}{5}^{28} * \frac{1}{5}^{-43} = \frac{1}{5}^{28+(-43)} = \frac{1}{5}^{-15}$

Therefore...

$\frac{1}{5}^{45} * \frac{1}{5}^{-60} - \frac{1}{5}^{28} * \frac{1}{5}^{-43}$

$\frac{1}{5}^{-15} - \frac{1}{5}^{-15} = 0$
