QUESTION:

Perform the following operation and express the answer in scientific notation.

9.80 x 10-3 + 1.60 × 10-4

Step-by-step explanation:

9.80 x 10-3 + 1.60 × 10-4

First let's apply exponent rule:

a^-b = 1/a^b

10^-3 = 1/10^3

= 9.8 x 1/10^3 + 10^-4 x 1.6

Let's apply exponent rule:

a^-b = 1/a^b

10^-4 = 1/10^4

9.8 x 1/10^3 + 1.6 x 1/10^4

9.8 x 1/10^3 = 9.8 x 0.001 = 0.0098

1.6 x 10^-4 = 1.6 x 0.0001 = 0.00016

= 0.0098 + 0.00016

= 0.00996

= 9.96 x 10³

Therefore 9.80 x 10-3 + 1.60 × 10-4 in scientific notation is 9.96 x 10³.
