Question

(1.5 X 5^4) * (2.2 X 5^-6) =
(1.5*2.2)*(5^4 * 5^-6)
3.3 * 5^-2
3.3*1
5^2
3.3
25
Would someone like to add the English explanation to this equation?

Answer 1

This is like scientific notation.. You are multiplying the whole parts together and then the parts that have 5 as a base together.

The whole parts are 1.5 and 2.2 hence (1.5*2.2)
The base parts are 5^4 and 5^-6 hence (5^4 * 5^-6)

1.5 * 2.2 = 3.3
5^4 * 5^-6 = 5^-2 (you add exponents when the bases are the same)

5^-2 = 1

25

so you have 3.3
