Answer:
Product [tex](21) ( x^{7})(y^{11})[/tex].
Step-by-step explanation:
Given : [tex](7x^{2} y^{3})(3x^{5} y^{8})[/tex].
To find : product .
Solution : We have given that
[tex](7x^{2} y^{3})(3x^{5} y^{8})[/tex].
Combine like terms
[tex](7 * 3) ( x^{2}*x^{5})(y^{3}*y^{8})[/tex].
By the exponential rule : if the base of two exponent is same then power must be added . [tex]x^{a} *x^{b} = x^{a+b}[/tex].
Then
[tex](21) ( x^{2+5})(y^{3+8})[/tex].
[tex](21) ( x^{7})(y^{11})[/tex].
Therefore, Product [tex](21) ( x^{7})(y^{11})[/tex].
