Answer 2

Answer:

☆Correct Question☆ :-

$\bf \:Find \: the \: value \: of \: { {((23 + {2}^{2}) }^{ \dfrac{2}{3} } + {(140 - 19)}^{ \dfrac{1}{2} } )}^{2}$

¤Solution¤ :-

$\bf \: { {((23 + {2}^{2}) }^{ \dfrac{2}{3} } + {(140 - 19)}^{ \dfrac{1}{2} } )}^{2}$

$\bf \: = { {((23 + 4) }^{ \dfrac{2}{3} } + {(121)}^{ \dfrac{1}{2} } )}^{2}$

$\bf\implies \: {( {27}^{ \dfrac{2}{3} } + 11)}^{2}$

$\bf\implies \: {(9 + 11)}^{2}$

$\bf\implies \: {20}^{2}$

$\bf\implies \:400$

$\bf\implies \: \: the \: value \: is \: 400$

● Remark :-

$\bf \: {(27)}^{ \dfrac{2}{3} }$

$\bf\implies \: {(3)}^{3 \times \dfrac{2}{3} }$

$\bf\implies \: {3}^{2} = 9$
