Answer 2

To simplify the expression (a² + 3ab - b²) • ab, we can distribute the ab term across each term inside the parentheses.

(a² + 3ab - b²) • ab = a² • ab + 3ab • ab - b² • ab

Using the properties of exponents, we can simplify the expression further:

a² • ab = a^(2+1) • b = a³ • b 3ab • ab = 3a^(1+1) • b^(1+1) = 3a² • b² -b² • ab = -b^(2+1) • a = -b³ • a

Substituting these simplified terms back into the expression, we have:

(a² + 3ab - b²) • ab = (a³ • b) + (3a² • b²) - (b³ • a)

So, the simplified expression is a³ • b + 3a² • b² - b³ • a.
