3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$5.1\times10^{-11}\times; 6.8\times10^{-15}$$

Answer

$$1*1/100000000000*;6.8*10^-15$$

Solution


Use Negative Power Rule: \({x}^{-a}=\frac{1}{{x}^{a}}\).
\[\begin{aligned}&1\times \frac{1}{{10}^{11}}\\&6.8\times {10}^{-15}\end{aligned}\]
Simplify  \({10}^{11}\)  to  \(100000000000\).
\[\begin{aligned}&1\times \frac{1}{100000000000}\\&6.8\times {10}^{-15}\end{aligned}\]
