Question

`4 * {8}^(x + 1) = {2}^(2x)`
Calculate the value of x​

Answer 1

x=-5

Explanation:

1. 2^2×2^3(x+1)=2^2x
2. since they have the same Base we equat the exponents
3. 2+3(x+1)=2x
4. 2+3x+3=2x group like terms
5. 3x-2x=-3-2
6. x=-5

Answer 2

`- 2`

Explanation:

2^2×2^3(x+1)=2^2x

same base cancel,you will get

2+3x+3=2x

take same variable then - or + you will get

`x = - 2`
