Question

The approximate diameters of Saturn and Neptune are listed below:
Saturn: 1.21 x 105 kilometers

Neptune: 4.95 x 104 kilometers

What's the difference between the diameters of the two planets? Express your answer
using either standard notation or scientific notation.

Answer 1

The difference between the diameters of the two planets is

$3.74 \times {10}^{-1}$

How to write in scientific notation

Given:

• Saturn = 1.21 x 10^5 kilometers

• Neptune = 4.95 x 10^4 kilometers

Difference in diameters in scientific notation = (4.95 x 10^4) - (1.21 x 10^5) +

= (4.95 - 1.21) × 10^(4 - 5)

= 3.74 × 10^-1

=

$3.74 \times {10}^{-1}$
