@Diana97 do you know what's $\frac{1}{a^{-5}}=??$

2. Diana97

no

3. ash2326

If I bring the denominator to the numerator the power will change its sign\ so $\frac{1}{a^{-5}}=a^5$

4. ash2326

@Diana97 do you get this part?

5. Diana97

yea

6. ash2326

we have $52.9/10^{-7}$ bring the denominator to numerator, would you?
