Sure. Here's an example.

$\sqrt{\dfrac{49}{81}}=\dfrac{7}{9}$

Another one might look like this. $\sqrt[4]{16} = 2$

And just one more

$\sqrt[3]{8000} = 20$

Answer:

x = 5.7 units

Step-by-step explanation:

By applying Sine rule is the triangle XYZ,

$\frac{\text{SinX}}{\text{WY}}=\frac{\text{SinY}}{\text{WX}}=\frac{\text{SinW}}{\text{XY}}$

$\frac{\text{SinX}}{\text{x}}=\frac{\text{SinY}}{\text{y}}=\frac{\text{SinW}}{\text{10}}$

$\frac{\text{Sin33}}{\text{x}}=\frac{\text{SinY}}{\text{y}}=\frac{\text{Sin107}}{\text{10}}$

$\frac{\text{Sin33}}{\text{x}}=\frac{\text{Sin107}}{\text{10}}$

$x=\frac{10\times(\text{Sin33})}{\text{(Sin107)}}$

x = 5.69

x ≈ 5.7 units

Answer:

133 1/3 km/hour

Step-by-step explanation:

Average speed is computed as ...

average speed = (total distance)/(total time)

= (80 km +120 km +200 km)/(2/3 + 1 + 1 1/3 hour) = 400 km/(3 hour)

= 133 1/3 km/hour
