Answer: 2^2x+6 = 2^6
Step-by-step explanation:
looking at the right of the equal since we can see:
64 is the same as 4^3
but since that answer isn't shown in the multiple choice but we can notice that 64 is the same as 2^6
Now that we know the left side is 2^6 we can see there is similar an answer in the multiple choice. But let's double check that the right side is the same.
Its pretty simple, just make 4 into 2^2 then distribute the exponent of 2 (times the 2 in the exponent to the rest to x+3)
2^2(x+3)
2^2x+6
