Question

find the answer of the question

Answer 1

$= > {4}^{x} + {4}^{x} + {4}^{x} + {4}^{x} = \frac{1}{16} \\ \\ = > 4 \times {4}^{x} = \frac{1}{16} \\ \\ = > {4}^{x} = \frac{1}{64} \\ \\ = > {4}^{x} = \frac{1}{ {4}^{3} } \\ \\ = > {4}^{x} = {4}^{ - 3}$

by comparison

=> X = -3
_________[ANSWER]

Answer 2

Answer-:

4^x+4^x+4^x+4^x= 1/16

=>4×4^x=1/16

=>4^x=1/16-4

=> 4^x= 1/16×1/4

=> 4^x= 1/64

=> 4^x= 1/4^3=4^(-3)

By comparison we get that x= -3
