simplify the expression?

Question

6n^6 m^2 n^14 m^7 6

Answer 1

I`m guessing you mean:
6*n^6*m^2*n^14*m^7*6

If this it it, then the solution is simple:
1. Put the similar variables together:
6*6*n^6*n^14*m^2*m^7

2. When you`re multiplying variables which are the same but have different exponents, you keep the variable and add the exponents.

36*n^(6+14)*m^(2+7)
36*n^20*m^9

Answer 2

It depends how you mean by simple. The shortest answer is:

36 n^20 m^9

achieved by combining the variables. However, if you're looking to simplify by prime factorisation, then the simplest is the slightly longer

2^2 3^2 n^20 m^9
