Question

Which expression is equivalent to 7a^2b + 10a^2b^2 + 14a^2b^3?

Answer 1

Answer:

Option: B is the correct answer.

           B) $a^2b(7+10b+14b^2)$

Step-by-step explanation:

We are given an algebraic expression in terms of the variable 'x' and 'y' as:

$7a^2b+10a^2b^2+14a^2b^3$

Now we are asked to find the expression that is equivalent to the above expression.

We could clearly observe that each of the term in the expression has a common term as: $a^2b$

Hence, we take out common this common term and write the remaining expression in  bracket as:

                    $a^2b(7+10b+14b^2)$

Answer 2

7a^2b + 10a^2b^2 + 14a^2b^3 =
a^2b (7 + 10b + 14b^2) <==
