Multiply (6.2x10 to the 8th power meters) by (4.7x10 to the -7 power meters)?

Question

Both measurements are in meters.

Answer 1

(6.2 * 10^8)(4.7 * 10^(-7))

(6.2 * 4.7) * 10^(8 - 7)

29.14 * 10

(2.914 * 10) * 10

2.914 * 10^(1 + 1)

2.914 * 10^2

or 291.4 m^2

Answer 2

so your question is:
(6.2 x 10^8 m) x ( 4.7 x 10^ -7 m)

so i jus used my graphing calculator and got:
291.4 m
and if u want significant digits ( that's what a lot of math and physics teachers want), your answer would be:

2.9 x 10^2 m
