Question

Which calculation can be used to find the value of p in the equation p3 = 8?

p equals cube root of 8
p equals 3 multiplied by the square root of 8
p equals 2 multiplied by square root of 8
p equals square root of 8

Answer 1

If u want to find the value of p in the equation p³ = 8, then the answer is p equals cube root of 8.

Answer 2

The correct option is 1. The value of p in the equation
`p^3=8` is
`\sqrt[3]{8}`,i.e., cube root of 8.

Explanation:

The given equation is

`p^3=8`

The power of p is 3. Taking cube root on both the sides, to find the value of p in the given equation.

`\sqrt[3]{p^3}=\sqrt[3]{8}`

`p=\sqrt[3]{8}`
`[\because \sqrt[n]{x^n}=x]`

The value of p in the equation
`p^3=8` is
`\sqrt[3]{8}`,i.e., cube root of 8.

Therefore the correct option is 1.
