C: 2x^5
Step-by-step explanation:
Leading coefficients are the numbers written in front of the variable with the largest exponent. Just like regular coefficients, they can be positive, negative, real, or imaginary as well as whole numbers, fractions or decimals. For example, in the equation -7x^4 + 2x^3 - 11, the highest exponent is 4.
Your answer would be 66^3 meaning 66 to the power of 3
