Question

(X^2)-(2^x)=1. Find x.​

Answer 1

Answer:

3

Step-by-step explanation:

Given that

${x}^{2} - {2}^{x} = 1 \\ => {x}^{2} - 1 = {2}^{x}$

Putting x = 3

$=> {3}^{2} - 1 = {2}^{3} \\ => 9 - 1 = 8 \: \: \: \: \\ = > 8 = 8 \: \: \: \: \: \: \: \: \: \: \: \:$

which is true.

Therefore x = 3
