1.5m6(-2m2)4 Use the rule (AB)N = ANBN 1.5m6(-2)4(m2)4 Use the fact that (-2)4 = +16 and the fact that (m2)4 = m8 1.5m6(16)m8 Rearrange the factors so that the numbers come first 1.5(16)m6m8 Multiply 1.5 by 16 and get 24 24m6m8 Add the exponents of m6 and m8 and get m14 24m14 Edwin AnlytcPhil@aol.com
