Verified answer

(4.5 × 10^4) × (0.6 × 10^–7) + (4.1 × 10^–1) =

2.7 * 10^-3 + 4.1* 10^-1

.0027 + .41 = .4127

Think of it this way...

[(4.5 x 0.6)x(10^4x10^-7)] + 4.1 x 10^-1

[2.7 x 10^-3] + (4.1 x 10^-1)

when mult with a neg power of ten, move the decimal to the left that many places.

Here it would be 0.0027. Same with the other one. 0.41

Now add them together = 0.4127

.4127
