Respuesta :

3x*7x=21x

you add the exponents when you multiple so the exponents 2+5=7

8+3=11

your answer is 21x^7y^11

The product of 7x²y³*3x²[tex]y^{8}[/tex] is 21[tex]x^{7} y^{11}[/tex]

What is exponents and power?

Power can be defined as an expression that represents repeated multiplication of the same number whereas exponent is the quantity that represents the power to which the number is raised.

Given expression:

7x²y³*3x²[tex]y^{8}[/tex]

Now, first using laws of exponents and powers

=21[tex]x^{7} y^{11}[/tex]

Hence, the product is 21[tex]x^{7} y^{11}[/tex].
