You can put this solution on YOUR website! The given expression is:
16^(2 - 5x) = 64^(x + 4)
16 can be written as 4^2 and 64 can be written as 4^3.
Hence, the above expression becomes:
42(2 - 5x) = 43(x + 4)
Since, the bases are same, we equate the powers.
2(2 - 5x) = 3(x + 4)
4 - 10x = 3x + 12
0 = 8 + 13x
13x = - 8
x =
Hence, the solution.
