Sederhanakan menggunakan sifat bilangan berpangkat dan rumusnya (16²)⁴x4³= 4³x7³ =

(16²)⁴x4³=
= ((2⁴)²)⁴ x (2²)³
= 2^32 x 2^6
= 2^38

4³x7³ =
= (4 x 7)³
= 28³

(n^a)^b = n^(a ×b)
n^b = (n × n)^b atau (n^a)^b
a^n × b^n = (a × b)^n

1)
(16^2)^4 × 4^3
= 16^(2 × 4) × (2^2)^3
= 16^8 × 2^6
= (2^4)^8 × 2^6
= 2^32 × 2^6 ← harus sama-sama 2
= 2^(32 +6)
= 2^38

2)
4^3 × 7^3 ← karena sama-sama ^3 maka:
= (4 × 7)^3
=28^3
