Answer 1

that answer is to correct to support

Answer 2

4/ 5 x 2^x

Explanation:

2^x +4-2^x / 5^2

First we multiply everything by 5^2/5^2

2^x + 4-2^x (5^2x) / (5^2)(5^2)

= 2^x + 4-2^x 5^2x we see 2 x 5^2

= 2^x+4-2 x 5^2x +5^2x / (5^2)(5^2x) 2^x cancels with 2^x as subtraction and 5^2x base cancels with top also

= 4/ 5 x 2^x
