simplify 21x^{-5}y^0

simplify

21 x^{- 5} y^{0}

\frac{21}{x ^{5}}

Solution steps

21 x^{- 5} y^{0}

Apply exponent rule:

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

x^{- 5} = \frac{1}{x ^{5}}

= 21 \cdot \frac{1}{x ^{5}} y^{0}

Apply exponent rule:

a^{0} = 1,

assuming

a \neq = 0

y^{0} = 1

= 21 \cdot \frac{1}{x ^{5}} \cdot 1

Multiply the numbers:

21 \cdot 1 = 21

= 21 \cdot \frac{1}{x ^{5}}

Apply the fraction rule:

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

= \frac{21 \cdot 1}{x ^{5}}

Multiply the numbers:

21 \cdot 1 = 21

= \frac{21}{x ^{5}}

1 - 2 x = - x - 3

6 x^{2} - 9 x + 18 = 0

4 x^{2} + 12 x = - 9
