Dear Student
(4)^3can be written as = (2 × 2)^3
= (2^2)^3
(5^2)^4 can be written as = 2^2×3 = 2^6 ... [∵(a^m)^n ) = a^mn
Then
= (2^8× a^5)/ (2^6× a^3)
=2^8-6 × a^5-3 ... [∵a^m÷a^n = a^m-n ]
= 2^2× a^2
= 2a^2 ... [∵(a^m)^n ) = a^mn
Thanks

Dear Student,
4³ can be written as (2×2)³.
(28 × a5 ) / (2×2)³ × a³
= 28-6 × a5-3
= 2² × a²
= (2a)² or 4a²
Hope it helps!
Thank you ✌️
