Question

How do you write 1 in scientific notation?

Answer 1

`1 = 1.0xx10^0` (in scientific notation)

Explanation:

Scientific notation requires that the mantissa (the first part) be written with a single non-zero digit to the left of the decimal point (unless the number is zero) multiplied by `10` with an exponent indicating how many positions the decimal point needs to be moved to the right (left if the exponent is negative) to get the "standard notation" value.

`1 = 1.0`

In this case the decimal point does not need to be moved (either direction), so the exponent is `0`.
