Answer 2

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
