simplify 2(-1/2)^2

Solution

simplify

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

Solution

\frac{1}{2}

+1

Decimal Notation

0.5

Solution steps

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

Apply exponent rule:

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

if

n

is even

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

= 2 (\frac{1}{2})^{2}

Apply exponent rule:

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

(\frac{1}{2})^{2} = \frac{1 ^{2}}{2 ^{2}}

= 2 \cdot \frac{1 ^{2}}{2 ^{2}}

1^{2} = 1

= 2 \cdot \frac{1}{2 ^{2}}

2^{2} = 4

= 2 \cdot \frac{1}{4}

2 \cdot \frac{1}{4} = \frac{1}{2}

= \frac{1}{2}
