Question

Mass of uranus is 8.68×10pwr25 kg and mass of earth is 5.97×10pwr24 kg.what is the total mass?

Answer 1

Step-by-step explanation:

8.68*10^25 + (5.97*10^24)

= 8.68*10^25 + 0.597*10^25

= 9.277 * 10^25 kg

Answer 2

The total mass of Uranus and the Earth is 9.277 × $10^{25}$ kg

Given:

Mass of Uranus is 8.68 × $10^{25}$ kg

Mass of Earth is 5.97 × $10^{24}$ kg

To find:

The total mass of Uranus and Earth.

Solution:

Mass of Uranus is 8.68 × $10^{25}$ kg

Mass of Earth is 5.97 × $10^{24}$ kg

To increase the exponent move the decimal point to the left of the number.

Therefore,

Mass of Earth = 0.597  × $10^{25}$ kg

The total mass of Uranus and Earth = 8.68 × $10^{25}$ + 0.597  × $10^{25}$ kg

The total mass of Uranus and Earth = 9.277 × $10^{25}$ kg
