simplify 4x^{-1/2}

Solution

simplify

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

Solution

\frac{4}{x ^{\frac{1}{2}}}

Solution steps

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

Apply exponent rule:

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

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

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

Apply the fraction rule:

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

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

Multiply the numbers:

4 \cdot 1 = 4

= \frac{4}{x ^{\frac{1}{2}}}

49 x^{2} - 140 x + 100

8(t+2)+7(t+2)-3(t-2)<0

8 (t + 2) + 7 (t + 2) - 3 (t - 2) < 0

2 = \frac{7}{2} (5 x + 6)
