(-8p^2q)(-4p^4q^5)=? (-8p2q)(-4p4q5) Put each factor in separate parentheses: (-8)(p2)(q)(-4)(p4)(q5) Rearrange them with numbers first, p's next, q's last (-8)(-4)(p2)(p4)(q)(q5) Multiply the numbers (-8)(-4) = +32 32(p2)(p4)(q)(q5) To multiply (p2)(p4), add the exponents p2+4 = p6 32p6(q)(q5) Give the q the exponent 1 32p6(q1)(q5) To multiply (q1)(q5), add the exponents q1+5 = q6 32p6q6 Edwin AnlytcPhil@aol.com
