Question

simplify:– (a²-b²)² ko plz bata do​

Answer 1

Answer:

$\Huge {\boxed {\boxed {\color{blue}{★}{\mathbb {\color{navy}{ANSWER}{\color{blue}{★}}}}}}}$

$\small \mathrm \color{skyblue}{Given, {( {a}^{2} - {b}^{2})}^{2} }$

$\small \mathrm \color{skyblue}{Using, {(a - b)}^{2} = {a}^{2} - 2ab + {b}^{2} }$

$\small \mathrm \color{skyblue}{ = > } {({a}^{2}) }^{2} - 2( {a}^{2} )( {b}^{2}) +{(b}^{2})^{2}$

$\small \mathrm \color{skyblue}{= > {a}^{4} - {2a}^{2} {b}^{2} + {b}^{4} }$

Answer 2

$\huge\sf\underline{AnsWeR}:$
$\bf \implies a^4+b^4-2a^2b^2$

$\huge\sf\underline{Solution}:$

$\sf{Using\: identity}:$
$\large\boxed{\tt (x-y)^2 = x^2+y^2-2xy}$
so,

$\implies$(a²-b²)² = a⁴+b⁴-2a²b²
