Simplify completely the quantity 14 times x to the 5th power times y to the 4th power plus 21 times x to the third power times y
timofeeve [1]

We have to simplify the given expression:

\frac{14x^5y^4+21x^3y^2}{7x^3y}

Dividing the terms of the numerator by the given term of denominator individually, we get

= \frac{14x^5y^4}{7x^3y}+\frac{21x^3y^2}{7x^3y}

By using the laws of exponent, a^m \div a^n = a^{m-n}, we get

= \frac{7 \times 2 x^5y^4} {7x^3y} + \frac{7 \times 3 x^3y^2}{7x^3y}

= \frac{2 x^5y^4} {x^3y} + \frac{3 x^3y^2}{x^3y}

= {2 x^{5-3}y^{4-1}} + 3 y^{2-1}

= {2 x^{2}y^{3}} + 3 y

Therefore, the simplification of the given expression is  {2 x^{2}y^{3}} + 3 y.

So, Option 3 is the correct answer.
