​

Answer 1

$(\frac{ 1 }{ 2 } p - \frac{ 3 }{ 4 }q) ^{ 5 }$

Answer 2

Question ⤵️

Find the square of the following numbers

$(\frac{7}{3} p - \frac{4}{5}q) ^{2}$

________________________

Solution ⤵️

$\huge\boxed{ \underline\texttt \green{fomula \: used}}$

$\bf \blue{ {(a - b)}^{2} = {a}^{2} - 2 \: ab + {b}^{2} }$

Given ,

$(\frac{7}{3} p - \frac{4}{5}q) ^{2}$

Putting the values given in the formula used:-

$\sf{(\frac{7}{3} p - \frac{4}{5}q) ^{2}}$

$\sf{ \implies \frac{49}{9} {p}^{2} - 2 \times \frac{7}{3} \times \frac{4}{5} + \frac{16}{25} {q}^{2} }$

$\sf{ \implies \frac{49}{9} {p}^{2} - \frac{2 \times 7 \times 4}{15} + \frac{16}{25} {q}^{2} }$

$\sf{ \implies \frac{49}{9} {p}^{2} - \frac{56}{15} + \frac{16}{25} {q}^{2}}$

Final Answer ⤵️

$\bf { \sf{ \implies} \bf \red {\frac{49}{9} {p}^{2} - \frac{56}{15} + \frac{16}{25} {q}^{2}}}$
