Question

Tolong please besok mau dikumpul

Answer 1

4 (2^(3x-2)) / 5 + 4^x . 2^x/(4.5) =1
4 (2^(3x-2)) / 5 + 4^(x-1) . 2^x /5 =1
4(2^(3x-2)) / 5 + 4 (4^(x-2) .2^x) /5 =1
4 (2^(3x-2) + 4^(x-2) . 2^x) / 5 =1
4(2^(3x-2) + 2^(2x-4) .2^x) /5 =1
4(2^(3x-2) + 2^(3x-4)) / 5=1
4(2^(3x-2) + 2^(3x-2) 2^(-2)) /5 =1
2^(3x-2) (1+2^(-2)) =5/4
2^(3x-2) (5/4) = 5/4
2^ (3x-2) =1
2 ^ (3x-2) =2^0
3x-2=0
3x=2
x=2/3
