Answer:
a) 2 and b) 3
Step-by-step explanation:
a) Here base is the same. So in order to both sides are equal, there powers should also equal.
Therefore, 2x = 4
i. e. x = 2
b) (3/4)^(x-1) = 9/16 = (3/4)^2
Now base became same. So again power should be equal, in order to make both sides equal.
x-1 = 2
x = 3
