# Thread: How do you multiply a negative exponent?

1. ## How do you multiply a negative exponent?

What would 2x multiplied by 6x^-4 be?

I know that 2x multiplied by 6x^4 is 12x^5.. you just add the positive exponents. Do you also add the exponents when working with negative exponents? So the answer would be 12x^(-4+1) = 12x^-3?

Thanks..

$2x^{1}\times 6x^{-4} = 2\times 6 \times x^{1+-4} = 12x^{-3}$
