Help me solve this

Question

(4.5 x 10^5)^3

I just need explanation for this equation

Answer 1

This is a compact way of writing (4.5*100,000)³ = 450,000³ = 9.1125 x 10¹⁶

You must first calculate 10⁵ and then multiply it by 4.5 to take care of what's in the parentheses. Once you have that, raise the product to the 3rd power.
