simplify 8x^{-2}

Solution

simplify

8 x^{- 2}

Solution

\frac{8}{x ^{2}}

Solution steps

8 x^{- 2}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

x^{- 2} = \frac{1}{x ^{2}}

= 8 \cdot \frac{1}{x ^{2}}

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{8 \cdot 1}{x ^{2}}

Multiply the numbers:

8 \cdot 1 = 8

= \frac{8}{x ^{2}}

Popular Examples

\frac{3}{4} x - 2 x \leq 1 + 2

4{x-(3x-2)}>3(x+5)-15

4 {x - (3 x - 2)} > 3 (x + 5) - 15

8 x^{2} + 21 = - 59 x

- x^{2} - 5 x + 6 = 0

simplify ((-2)^8*5^3)/(5^4*2^{10)*10}simplify

\frac{( - 2 ) ^{8} \cdot 5 ^{3}}{5 ^{4} \cdot 2 ^{10} \cdot 10}
