simplify

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

Solution

\frac{4}{49}

+1

Decimal Notation

Solution steps

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

Apply exponent rule:

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

if

n

is even

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

= (\frac{2}{7})^{2}

Apply exponent rule:

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

= \frac{2 ^{2}}{7 ^{2}}

2^{2} = 4

= \frac{4}{7 ^{2}}

7^{2} = 49

= \frac{4}{49}
