The moon is about 240,000 miles from Earth. What is this distance written as a whole number multiplied by a power of ten?

Question

I really need a good answer I am really stuck on this please help. I tried my best and don't know if I'm right.

Answer 1

240,000 = 24 x 10^4

24 followed by 4 zeros = 24 x 10⁴

Just make the number of zeroes be the exponent for 10

24 = 24 x 10^0

240 = 24 x 10^1

2400 = 24 x 10^2

24000 = 24 x 10^3

240,000 = 24 x 10^4 miles
