Question

Scientific notation of 10 to the power of negative 9 times (2times 10 square)squared

Answer 1

First, we expand
`(2 \cdot 10^2)^2` as a regular scientific notation expression. By squaring each term separately, we find that this is equal to
`4 \cdot 10^4`.

Then, we multiply the other term:
`4 \cdot 10^4 \cdot 10^(-9)`. Note that multiplying exponents together results in adding the powers, so we have a final answer of
`4 \cdot 10^(-5)`.
