Question

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

Answer 1

2^x • 4^(x+5) = 4^(2x-1)

The trick to solving this is to CHANGE THE BASE to a common one, in this case 2.

2^x • (2²)^(x+5) = (2²)^(2x-1)

2^x • (2)^(2x+10) = (2)^(4x-2)

(2)^(3x+10) = (2)^(4x-2)

Since the bases are the same, the powers must also be the same.

(3x+10) = (4x-2)

x = 12
