Find the sum of difference 15m²n³-12m²n³+8m²n³=
Answer (1)
Answer:11 m²n³Step-by-step explanation:In order to add the terms, we must first group the terms with the same literal coefficients. In this expression, we can see that all the terms contain the literal coefficient m²n³. Hence, we can simply add or subtract their numerical coefficients and keep their literal coefficient:15m²n³-12m²n³+8m²n³= (15-12+8) m²n³= 11m²n³
