Question

9^2a = (3 root 81 ) -6/b =27 root find the values of a and b

Answer 1

Answer:

Square of a number.

If a natural number m can be expressed as n2 (where n is a natural number), then m is the square root or perfect square.

i.e. if m = n2 (m, n – natural numbers)

E.g. 81 = 3 × 3 × 3 × 3

= 32 × 32 = (3 × 3)2 = 92

Hence, 9 is the square root of 81
