An equivalent fraction to the given expression
7a^2b+10a^2b^2+14a^2b^3 is
a^2b(7+10b+14b^2)

Explanation:

Given : expression
7a^2b+10a^2b^2+14a^2b^3

We have to write an equivalent fraction to the given expression
7a^2b+10a^2b^2+14a^2b^3

Equivalent expressions are expression having same value but they look different and it can be obtained by taking out common factors from each term of expression. When we take product we get back the same expression.

Consider the given expression
7a^2b+10a^2b^2+14a^2b^3

Since, each term of given expression has
a^2b term common,

So taking it out , we are left with ,


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

Thus, option (2) is correct.

An equivalent fraction to the given expression
7a^2b+10a^2b^2+14a^2b^3 is
a^2b(7+10b+14b^2)
