Question

Which calculation can be used to find the value of y in the equation y3 = 27?

y=y equals 27 over 3
y=y equals cube root of 27
y=y equals square root of 27 over 3
y=y equals square root of 27

Answer 1

y=y 3equals cube root of 27

Explanation:

the guy on top is right

Answer 2

the value of y is 3

Explanation:

Given an equation:
`y^3=27`

Any term that has a power of 3 is known as a cube term.

A cube root is of any number that has an inverse of power 3, i.e, the cube root of x is denoted by
`\sqrt[3 ]{x}` or
`(x)^(1)/(3)`

To solve the value of y :

`y^3=27`

`y=\sqrt[3]{27}` or we can write this as

`y=\sqrt[3]{3* 3* 3}`

On simplify:

y=3

therefore, the value of y is 3 using the calculation of y equals cube root of 27.
