Answer 1

Haven't we done this, already?

8.6 E0 = 8.6
8.6 E1 = 86
8.6 E2 = 860
8.6 E3 = 8600

Can you continue?

Each "E" is a power of 10.

Answer 2

I still dont understand.

Answer 3

Perhaps an expanded version?

8.6 E0 = 8.6 * 10^0 = 8.6*1 = 8.6
8.6 E1 = 8.6 * 10^1 = 8.6*10 = 86
8.6 E2 = 8.6 * 10^2 = 8.6*100 = 860
8.6 E3 = 8.6 * 10^3 = 8.6*1000 = 8600

Can you continue?

Each "E" is a power of 10.
