Question

18^5×(5^2)^-4×(3^-4)^2 simplify​

Answer 1

Answer:

2^5 x 3^2 x 5^-8

Step-by-step explanation:

= 18^5 x 5^(2 x -4) x 3^(-4 x 2)

= 18^5 x 5^-8 x 3^-8

= (2 x 3^2)^5 x 5^-8 x 3^-8

= 2^5 x 3^(5 x 2) x 5^-8 x 3^-8

= 2^5 x 3^10 x 5^-8 x 3^-8

= 2^5 x 3^(10+(-8)) x 5^-8

= 2^5 x 3^2 x 5^-8
