Question

Plis pake jalannya ya

Answer 1

3.1
27^(2x-4) = 9^(x-3)
3^3^(2x-4) = 3^2^(x-3)
6x - 12 = 2x-6
4x = 6
x = 6/4

3.2
(1/8)^(4x+5) = 32^(4x-3)
2^(-3)^(4x+5) = 2^5^(4x-3)
-12x - 15 = 20x -15
-32x = 0
x = 0

3.3
(4^(2x+3))^2 = (V(8^(3x+6)))^2
4^(4x+6) = 8^(3x+6)
2^2^(4x+6) = 2^3^(3x+6)
8x + 12 = 9x + 18
-x = 6
x = -6

3.4
5^(x+2) = (1/5)^(x+2)
x+2 = -x - 2
2x = -4
x = -2

semoga benar yaa ^^
