Question

13.
Find the value of x, if 2^2x+2 = 4^2x-1​

Answer 1

(2²)x+2 = (4²)x-1

4x+2 = 16x-1

16x-4x = 2+1

12x = 3

x = $\frac{3}{12} = \frac{1}{4}$

Answer 2

$2 {}^{2x + 2} = 4 {}^{2x - 1 } \\ 2 {}^{(2x + 2)} = 2 {}^{2(2x - 1)} \\ 2x + 2 = 4x - 2 \\ 2x = 4 \\ x = 2.......is \: your \: answer$

pls mark me as brain list pls pls
