Question

using identities evaluate it
704​

Answer 1

$\huge\mathtt{\underline{\underline{\red{SOLUTION:-}}}}$

By using the identity of :-

$\sf\implies (a+b){}^{2}$

where in the place of a=700 and the place of b =4

Then :-

we know that $\sf (a+b){}^{2}=a{}^{2}+b{}^{2}+2ab$

Now :-

$\mathtt{\underline{\underline{\red{According\:to\: question:-}}}}$

$\sf\longrightarrow (700+4){}^{2}\\ \\ \sf\longrightarrow (700){}^{2}+(4){}^{2}+2\times700\times4\\ \\ \sf\longrightarrow 490000+16+5600\\ \\ \sf\implies 4,95,616$

$\boxed{\red{\bold{4,95,616}}}$

✨$\mathbb{SOLUTION}$

▬▬▬▬▬ஜ۩۞۩ஜ▬▬▬▬▬▬

By using identity of,

$= > (a + b)^{2}$

Where in place of a=700 and the place of b=4

THEN,

WE KNOW THAT,

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

ACCORDING TO QUESTION:

$= > (700 + 4)^{2}$

$(700) {}^{2} + (4 {}^{2} ) + 2 + \times 700 \times 4$

$490000 + 16 + 5600$

$= > 495616$
