Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$(\frac{2}{7})^{2+3}\div(\frac{2}{7})^{5^{-}}$$

Answer

$$729+3/27^(1/5^)$$

Solution


Simplify  \({27}^{2}\)  to  \(729\).
\[729+\frac{3}{{27}^{{5}^{-}}}\]
Use Negative Power Rule: \({x}^{-a}=\frac{1}{{x}^{a}}\).
\[729+\frac{3}{{\sqrt[5}^{]{27}}}\]
