Answer:
12)5^x=125
13)5
Explanation:
The base on the logarithm is also the base of the exponent so 5^something=something else and 125 is the number in the logarithm it is put on the other side so 5^something=125 and as the something is x the answer is 5^x=125
The second question uses the same logic 2^y=32 so y must be 5
