Answer 2

A) =6,440,000
=6.44x10^6 (put a decimal after the first number, write down the other numbers greater than 0, then count all the numbers from te decimal, which in this case 6)

If you get a number like 0.0007 that means the exponent will be negative so it would be 7x10^-4

Hope that helped:)
