Question

Tolong teman teman saya lupa bagian ini

Answer 1

1)
(2)^3(x+12) = (2)^ 1/3(3x+7)
3(x+12) = 1/3 (3x+7)
9(x+12) = 3x+7
9x + 108 = 3x +7
6x = - 101
x = -101/6
.
2)
(2)^2(x+3) =(2)^3/4(x+5)
2(x+3) = 3/4(x+5)
8(x+3) = 3(x+5)
8x + 24 = 3x + 15
5x = - 9
x = -9/5
.
3)
(9)^  1/3.(5-x)  . (3)^(x+2) = 27
. (3)^ 2/3(5-x) . (3)^(x+2) = (3)^3
2/3 (5-x) + x+2 = 3
2( 5-x) + 3x + 6 = 9
10 - 2x + 3x +6  =9
x +16  = 9
x = -7
