Question

determine the value of x in each of the following
I want to know the answers of a, c
with working​

Answer 1

So this question is Easy. Please Mark Brainliest.

(i)  {(3)^3}^7 = 3^7x

So on simplifying, 3^21=3^7x

21=7x

x=3

(ii) (47)^x / (47)^21 = (47)^45

The Base are same i.e. 47. So powers will subtract.

Therefore, (47)^x-21 = (47)^45

Now base again are same. We will put the powers equal.

x-21=45

x=66.

Thank You.
