Question

Solve the equation v^3=80

Answer 1

Answer:
`v=2\sqrt[3]{10}` or 4.3

Explanation:

Step 1 Take the cube root of both sides.

`v=\sqrt[3]{80}`

​

Step 2 Simplify
`3√(80)` to
`2\sqrt[3]{10}`

`v=2\sqrt[3]{10}`

​

Decimal Form: 4.3

Answer 2

4.31

Explanation:

Find the cube root of both sides of the equation.

`^3√(v^3)` =
`^3√(80)`

The cube root will cancel out the cubed in the variable.

v =
`^3√(80)`

Find the cube root of 80. I rounded to the nearest hundredth.

v = 4.31
