Question
Mixed Practice(a) $15 n^{10}+3 n^{10}$(b) $15 n^{10}-3 n^{10}$(c) $15 n^{10} \cdot 3 n^{10}$(d) $15 n^{10} \div 3 n^{10}$
Step 1
Since the terms are like terms (they have the same variable and exponent), we can simply add the coefficients. So, $15 + 3 = 18$. Therefore, the answer is $18n^{10}$. Show more…
