Question

Write 9.31 x 10 4 as an ordinary number.

Answer 1

93100

Explanation:

When x10^4 comes, this means that the decimal point moved four digits back so to find the ordinary number you have to do the reverse, go four digits front.

93.1x10^3 (1 digit front)

931x10^2 (1 more digit front)

If the decimal points moved completely, add 0s till you get to no x10.

9310x10^1 (1 more digit front)

93100 (1 more digit front)

Totally you have to go 4 digits front and add 0s if necessary,

I hope this helps.
