Answer:
x=2
Step-by-step explanation:
2^(2x+2)=4^(2x-1)
4=2^2
Instead of 4 we can write 2^2 so that the base numbers will be 2
2^(2x+2)=(2^2)^(2x-1)
So we get 2 raise to 2x +2=2 raise 2 all raise to 2x-1
We have studied a raise to m all raise to n is a raise to m*n
(a^m)^n=a^(mn)
Here the m is 2 and n is 2x-1
mn=2 (2x-1)
mn=4x-2
Thus we will get
2^(2x+2)=2^(4x-2)
The base numbers are equal so the power will also be equal....
2x+2=4x-2
Solve......
2+2=4x-2x
4=2x
2x=4
x=4/2
x=2
Hope it helps ...
plse mark me as brainliest......
