Answer:
[tex]2a+a^3=b[/tex]
Step-by-step 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 [tex]a^3[/tex]
Also note "is" means "equal" and "of" means "multiplication.
Twice a increased by cube of a means both parts are summed so we have:
[tex]2a+a^3=b[/tex]\
This is the formula/equation
Answer:
The required expression is 2a+a³=b.
Step-by-step 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.
