(0) = pangkat

Answer 1

1/25 × 5^4 × 5^-2 :1/25 × 1/5
= 1/5^2 × 5^4 × 5^-2 : 1/5^2 × 1/5
= 5^-2 × 5^4 × 5^-2 : 5^-2 × 5^-1
=5^-2 × 5^4 × 5^-2 × 5^2 ×5^-1
=5^1 = 5


16 × 4^7 × 4^-5 : 1/4 × 1/64 × 4^-2
= 4^2 × 4^7 × 4^-5 :4^-1 × 4^-3 × 4^-2
=4^2 × 4^7 × 4^-5 × 4^1 × 4^-3 × 4^-2
=4^0 = 1

^ = pangkat
