Question

Twice "a" increased by the cube of "a" equals b.

Please translate into an equation or formula

Answer 1

The required expression is 2a+a³=b.

Explanation:

Consider the provided phrase.

Twice "a" increased by the cube of "a" equals b.

Twice "a" can be written as: 2×a=2a

For increase use a positive sign.

The cube of "a" can be written as: a³

Thus the combination of the above expressions are:

2a + a³

It is given that the expression is equal to b.

Thus the required expression is 2a+a³=b.

Answer 2

`2a+a^3=b`

Explanation:

Let's do it part by part:

Twice "a":

This means 2 times a, or 2*a

Cube of "a":

This means a cubed, so a to the power 3, or
`a^3`

Also note "is" means "equal" and "of" means "multiplication.

Twice a increased by cube of a means both parts are summed so we have:

`2a+a^3=b`\

This is the formula/equation
