Question

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

Answer 1

Answer:

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

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

Step-by-step 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
