simplify (-1/(2sqrt(7-x)))^2

Solution

simplify

(- \frac{1}{2 7 - x})^{2}

Solution

\frac{1}{4 ( 7 - x )}

Solution steps

(- \frac{1}{2 7 - x})^{2}

Apply exponent rule:

(- a)^{n} = a^{n},

if

n

is even

(- \frac{1}{2 7 - x})^{2} = (\frac{1}{2 7 - x})^{2}

= (\frac{1}{2 7 - x})^{2}

Apply exponent rule:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

= \frac{1 ^{2}}{( 2 7 - x ) ^{2}}

1^{2} = 1

= \frac{1}{( 2 7 - x ) ^{2}}

Simplify

(2 7 - x)^{2} : 4 (7 - x)

= \frac{1}{4 ( 7 - x )}
