Question

How many terms are in the expression 12+r to the third power

Answer 1

There are 4 terms in the expansion of the given expression
`(12+r)^3`

Therefore
`(12+r)^3=1728+r^3+432r+48r^2`

Explanation:

Given expression is
`(12+r)^3`

To find how many terms in the expansion of the given expression :

`(12+r)^3=12^3+r^3+3(12)^2r+3(12)r^2`

`=1728+r^3+3(144)r+48r^2`

`=1728+r^3+432r+48r^2`

Therefore
`(12+r)^3=1728+r^3+432r+48r^2`

There are 4 terms in the expansion of the given expression
