simplify (4x)^{-1/2}*(9x)^{1/2}

simplify

(4 x)^{- \frac{1}{2}} \cdot (9 x)^{\frac{1}{2}}

\frac{3}{2}

Solution steps

(4 x)^{- \frac{1}{2}} (9 x)^{\frac{1}{2}}

Simplify

(4 x)^{- \frac{1}{2}} : \frac{1}{2 x ^{\frac{1}{2}}}

= \frac{1}{2 x ^{\frac{1}{2}}} (9 x)^{\frac{1}{2}}

Simplify

(9 x)^{\frac{1}{2}} : 3 x^{\frac{1}{2}}

= \frac{1}{2 x ^{\frac{1}{2}}} \cdot 3 x^{\frac{1}{2}}

Apply the fraction rule:

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

= \frac{1 \cdot 3 x ^{\frac{1}{2}}}{2 x ^{\frac{1}{2}}}

Multiply the numbers:

1 \cdot 3 = 3

= \frac{3 x ^{\frac{1}{2}}}{2 x ^{\frac{1}{2}}}

Cancel the common factor:

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

= \frac{3}{2}

75 \cdot 3

- 4 (x + 6) = 12 x + 4

(x - 5)^{2} = 17

∣ 5 x + 3 ∣ = 17

36 y^{2} - 1
