Question

(1.2 x 10-4) + (2.4 x 10-3)

Answer 1

Answer:

29

Step-by-step explanation:

(1.2 x 10-4) + (2.4 x 10-3)

Simplify

1.2 x 10- 4 = 8

2.4 x 10- 3 = 21

Add both sums to get 29!

SCIENTIFIC NOTATION

2.9 x 10 to the 1st power

Move the decimal over to make a number less than ten, so that makes 2.9 and 10 to the 1st because you moved the decimal once! Hope this is better
