Answer 1

`6.3 * 10^2 = 630`

Explanation:

Numbers expressed in scientific notation follow the general form

`color(blue)(a * 10^b)" "`, where

`a` - the mantissa, which represens the significant digits of the number;
`b` - the exponent of the base;

In your case, the mantissa is equal to `6.3` and the exponent of the base is equal to `2`.

To convert this number from scientific notation to standard notation you need to move the decimal point to the right because you're dealing with a positive exponent.

As you move the decimal point to the right, you decrease the exponent by `1` for every position the decimal dot changes. You do this until the exponent is equal to zero.

This means that you would get

`6.3 * 10^(2) -> 63 * 10^1 -> 630 * 1 = 630`

The standard notation for `6.3 * 10^2` is `630`. Keep in mind that you need to have the same number of sig figs for both numbers.
