Answer:
1. x = 4
2. x = 0
3. x = 10
4. x <= - 2
5. x < - 2
solution:
1. 3^x = 81
3^x = 3^4
x = 4
2. 169^x = 13^x
13^(2x) = 13^x
2x = x
2x - x = 0
x = 0
3. 5^(x-7) = 5^3
x-7 = 3
x = 7 + 3
x = 10
4. (4/6)^x >= (6/4)^2
(4/6)^x >= (4/6)^(-2)
x <= - 2
5. 5^x > 25 ^(x+1)
5^x > 5 ^(2x + 2)
x > 2x + 2
-x > 2
x < - 2
