Question

Find the value of (48)^2 by using indentities

Answer 1

Step-by-step explanation:

$\huge \fbox \pink {A} \fbox \blue {n} \fbox \green {s} \fbox \red {w} \fbox \purple {e} \fbox {r}→$

We know,

$( {a - b})^{2} = {a}^{2} + {b}^{2} - 2ab$

$\huge{\bold{\star{\fcolorbox{black}{red}{Solution→}}}}$

Using the ldentity, we get :-

${48}^{2} = ( {50} - 2)^{2}$

$=> {50}^{2} + {2}^{2} - 2 \times 50 \times 2$

$=>2500 + 4 - 200$

$=>2304$
