Question

Is this the correct first step?

Answer 1

The solution is

Explanation:

No

`8^3^x^-^4` =
`2^2^x^+^9`

`2^3^(^3^x^-^4^)`=
`2^2^x^+^9`

multiply 3 with 3x - 4 in the power then we get

`2^9^x^-^1^2`=
`2^2^x^+^9`

hence 2 is same so we compare the power values then we get

9x-12 =2x +9

9x - 2x = 9+12

7x = 21

divide by 7 on both sides we get

7x / 7 = 21 / 7

x = 3
