Answer:

$\huge{\underline{\underline{Given→}}}$

• $\sf\green{Equation=(7°-4°)(7°+4°)}$

$\huge{\underline{\underline{To\:Find→}}}$

$\sf\pink{→Expansion\:of\:the\:given\:equation.}$

$\huge{\underline{\underline{Answer→}}}$

$→(7°-4°)(7°+4°)$

$→(7°)^2-(4°)^2$

$→49°-16°$

$→33°$

$\sf{\boxed{\boxed{\red{→33°✔}}}}$

$\bold{\underline{\underline{Identity\:used→}}}$

$(x - y)(x + y) = {x}^{2} - {y}^{2}$
