I can't solve that by graphing but I'll try logarithms:
log(7)4 = 2x
log(7)/log(4) = 2x
1.403 = 2x
x = 0.702

Answer:

0.702 is the solution of this function.

Step-by-step explanation:

We have

           [tex]4^{2x}=7\\\\4^{2x}-7=0[/tex]

Let us plot [tex]y=4^{2x}-7[/tex] when y value of this function is zero then that is the solution of [tex]4^{2x}=7[/tex]

Refer the figure given, we have at x = 0.702 y value is zero that is 0.702 is the solution of this function.
