For this case we must find the product of the following expression:[tex]8y ^ 3 (-3y ^ 2) =[/tex]We have to by law of signs of multiplication:[tex]+ * - = -[/tex]Also, by definition of multiplication of powers of the same base, we put the same base and add the exponents, then the expression is rewritten as:[tex]-24y ^ {3 + 2} =\\-24y ^ 5[/tex]Answer:[tex]-24y ^ 5[/tex]
