4 in the power of 6
4^6
When dividing like bases we subtract the exponets.
And if we divide to like base and we get that number in the power of 0 that mean that the exponents of the numbers were the same.
With equation:
4^6 / 4^x = 4^0
2^12 / 2^2x = 4^0
2^12-2x =4^0
2^12-2x= 2^0
12 - 2x = 0
-2x = -12
X = -12/-2
X = 6
