8n6 x -7n2 =?
Since we are looking at just the multiplication of the terms 8n6 and -7n2, with the only variable being 'n', we simply start by multiplying the 8 and the -7, which equals -56. Then, we need to go back to our rules on multiplying exponents of the same variable (in this case 'n'). You will find that we simply add the exponents of the same variable to multiply them; thus, n6 x n2 = n6+2 = n8.
Therefore, our simplified answer would be -56n8 . Hope that helps! :)
