Question

Q:4. Find the values of n in each of the following:
(i) 52n * 53 = 511
(ii) 9 x 3n = 37
(iii) 8 x 2n+2 = 32
(iv) 72n+1 ÷49 = 73
(v) (3/2)4 * (3/2)5 = (3/2)2n+1
(vi) (2/3)10×{(3/2)2}5 = (2/3) 2n - 2​

Answer 1

Answer:

Given, 5

2n

×5

3

=5

11

5

2n+3

=5

11

Could be written as 2n+3=11
