3^(-2x + 2) = 81? log(3^(-2x + 2)) = log(81) (-2x+2)log(3) = log(81) -2x = log(81)/log(3) - 2 x = (-1/2)(log(81)/log(3)) + 1

-2+5=3

G(x) = log(2x) + 2, obviously!

2 log(x) + 3 log(x) = 105 log(x) = 10log(x) = 10/5 = 210log(x) = (10)2x = 100

x = 5, y = -1

You can't solve it. But you can simplify it to get: 4x+y=2

7x + 2 = 5,6

log1 + log2 + log3 = log(1*2*3) = log6

log(x) + log(2) = log(2)Subtract log(2) from each side:log(x) = 0x = 100 = 1

-1 plus 1 = 0 plus 1 =1
