what activities are in the pre writing stage of the writing process?
The expression (3a^2 b^4 c^2)^2 (2a^4 b^2 c^4)^3 equals na^r b^s c^t It ask what n, the leading coefficient is and I think it is 72? and to find the exponents r s and t would you just multiply it but whatever number is on the outside? or do I need to find the derivative??
f(x)= 7-5x^4 How would find the the absolute max and the x value? I think you have to take the derivative which is -20x^3 but then I am lost??
