How do I solve this exponent problem? I understand the exponent rules, but I getting 1 but 1 is not the answer! I don't want anyone to solve the problem for me, I want to learn how to solve this type of problem. Thank you! Solve the equation: -8=-3-6 (3sqrtx^2) Thanks again!

calculus
The voltage V (volts), current I (amperes), and resistence R (ohms) of an electric circuit are related by the equation V=IR. Suppose that V is increasing at a rate of 3 volt/sec while I is decreasing at a rate of 1/8 amp/sec. Let t denote time in seconds. Determine the rate at...
