Question

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

Answer 1

The distance is
240,000 = 24 x 10,000

Note that
10 = 10¹
100 = 10 x 10 = 10²
1,000 = 10 x 10 x 10 = 10³
10,000 = 10 x 10 x 10 x 10 = 10⁴

Therefore
240,000 = 24 x 10,000 = 24 x 10⁴
