Question

What is the product? (7x2y3)(3x5y8)

Answer 1

Answer:

Product $(21) ( x^{7})(y^{11})$.

Step-by-step explanation:

Given : $(7x^{2} y^{3})(3x^{5} y^{8})$.

To find : product .

Solution : We have given that

$(7x^{2} y^{3})(3x^{5} y^{8})$.

Combine like terms

$(7 * 3) ( x^{2}*x^{5})(y^{3}*y^{8})$.

By the exponential rule : if the base of two exponent is same then power must be added . $x^{a} *x^{b} = x^{a+b}$.

Then

$(21) ( x^{2+5})(y^{3+8})$.

$(21) ( x^{7})(y^{11})$.

Therefore, Product $(21) ( x^{7})(y^{11})$.
