Can the following expressions be written in a simpler forms? If yes, write an expression for each problem. If not, explain why why not. exercise 2⁷/4²= 2⁷/2⁴=

Both of them can be simplified.

Recall that 4 = 2^2.

2^7 / 4^2 = 2^7 / (2^2)^2 = 2^7 / 2^4 = 2^(7-4) = 2^3 = 8

Similarly, 2^7 / 2^4 = 2^(7-4) = 2^3 = 8

The answers to both exercises are 8.
