Use the order of operations

Explanation:

First combine the terms in the parenthesis

$\frac{{(- 7)}^{2}}{{- 3 - (- 10)}^{2}} = \frac{49}{{(+ 7)}^{2}}$ $( -7)^2 / {-3-(-10) }^2 = 49 /(+7)^2$

a negative time a negative = a positive
$(- 7) \times (- 7) = + 49$ $( -7) xx ( -7) = + 49$

$(-) \times (- 10) = + 10$ $( -) xx ( - 10) = + 10$

$- 3 + 10 = + 7$ $-3 + 10 = +7$

$\frac{49}{{(+ 7)}^{2}} = \frac{49}{49}$ $49/(+7)^2 = 49/49$

$\frac{49}{49} = 1$ $49/49 = 1$

$1$ $1$

Explanation:

${(- 7)}^{2} \div {(- 3 - - 10)}^{2}$ $(-7)^2-:(-3- -10)^2$

$a a a a a a a a a a a a a a$ $color(white)(aaaaaaaaaaaaaa)$ $- 3$ $-3$
$a a a a a a a a a a a a a$ $color(white)(aaaaaaaaaaaaa)$ $- 10$ $-10$ $-$ $-$
$a a a a a a a a a a a a a$ $color(white)(aaaaaaaaaaaaa)$ $- - -$ $---$
$a a a a a a a a a a a a a a$ $color(white)(aaaaaaaaaaaaaa)$ $+ 7$ $+7$

$:.(-7 xx -7)-:(7)^2$

$:.(-7 xx -7)-:7 xx 7$

$:.49-:49=1$
