Question

(a) The Singapore Flyer cost $240 000 000 to build.
Write 240 000 000 in standard form.

(b) The planet Jupiter has a mass of 1.9 * 10^27 kg. The planet Earth has a mass of 5.97 * 10^24 kg.

How many more times is the planet Jupiter heavier than the planet Earth? Give your answer in standard form.

Answer 1

(a) 240 000 000 in standard form is 2.4 * 10^8.

(b) To find out how many more times Jupiter is heavier than Earth, we need to divide the mass of Jupiter by the mass of Earth.

The division would be: (1.9 * 10^27) / (5.97 * 10^24) = 3.18 * 10^(27-24) = 3.18 * 10^3.

So, the planet Jupiter is 3.18 * 10^3 times heavier than the planet Earth.
