Im not sure how to do this.
(5q^3)(-12q^-4n^4)
So far what i did was multiply 5 by -12 to get -60. Then q^3 by q^-4 to get q^-1. I don't know what to do after this. Maybe you could tell me what I should do and then I can solve it. I was taught exponent rules but I'm not quite sure about this.
My Final Answer:
-60q^-1n^4
Yes, that is it.
-60q-1n4
To simplify the expression (5q^3)(-12q^-4n^4), you have correctly multiplied the coefficients and combined the variables.
First, you multiplied 5 by -12 and got -60, which is the coefficient of the simplified expression.
Next, you multiplied q^3 by q^-4. When multiplying two terms with the same base (in this case, q), you add the exponents: q^3 * q^-4 = q^(3 + -4) = q^(-1).
Finally, you have n^4 as a separate variable, which remains unchanged since there are no other variables to combine it with.
So, combining the coefficient and the variables, the simplified expression is -60q^(-1)n^4. This means that your final answer -60q^-1n^4 is correct. Well done!
