Question

Express three times the distance between Earth and Sun in scientific notation if distance between the Earth and the Sun is approximately 151.85 million kilometers​

Answer 1

So the distance between the earth and the sun is 150 million kilometers. In scientific notation, you have to find the number between 1 and 10, then multiply it by 10x . So the number between 1 and 10 in 150,000,000 is 1.5, and a number of decimal points is 8. So the answer is 1.5⋅108
