Question

simplify,,,,. [( 3/7 )-3 ]4​

Answer 1

Step-by-step explanation:

$\underline{{\left[{{\left({\frac{3}{7}}\right)}^{\mathrm{{-}}{3}}}\right]}^{4}}$

=> $\underline{{\left({\frac{3}{7}}\right)}^{\mathrm{{-}}{3}\mathrm{\times}{4}}}$

=> $\underline{{\left({\frac{3}{7}}\right)}^{\mathrm{{-}}{\mathrm{12}}}}$

=> $\underline{{\left({\frac{7}{3}}\right)}^{\mathrm{12}}}$

=> $\frac{{7}\mathrm{\times}{7}\mathrm{\times}{7}\mathrm{\times}{7}\mathrm{\times}{7}\mathrm{\times}{7}\mathrm{\times}{7}\mathrm{\times}{7}\mathrm{\times}{7}\mathrm{\times}{7}\mathrm{\times}{7}\mathrm{\times}{7}}{{3}\mathrm{\times}{3}\mathrm{\times}{3}\mathrm{\times}{3}\mathrm{\times}{3}\mathrm{\times}{3}\mathrm{\times}{3}\mathrm{\times}{3}\mathrm{\times}{3}\mathrm{\times}{3}\mathrm{\times}{3}\mathrm{\times}{3}}$

=> $\frac{\mathrm{13841287201}}{\mathrm{531441}}$ Ans.
