Question

Q2. Evaluate the following (Just apply the rules of powers and exponents):
i (5/3}²X {7/5)‐⁵X (3/7)²​

Answer 1

(5/3)^2 ×(3/7)^2×(7/5)^-5

= (5/3×3/7)^2 × (7/5)^-5 ( : a^m × a^n = a ^ mn)

= (5/7)^2 × (7/5)^-5

= (5/7)^2 × (5/7)^5 ( (a/b)^-n = (b/a)^n )

= (5/7)^7 ( a ^ m × a ^ n = a ^ m+ n )

= (5/7) ^ 7
