Step 1: Recall that the antiderivative of a function f(x) is a function F(x) such that F'(x) = f(x). To find the antiderivative of f(x) = 100x^99, we will use the power rule for integration.
Step 2: The power rule for integration states that for any term x^n, the antiderivative is (x^(n+1))/(n+1) + C, where C is the constant of integration. Apply this rule to f(x) = 100x^99.
Step 3: Integrate 100x^99. Increase the exponent by 1 (from 99 to 100) and divide the coefficient (100) by the new exponent (100). This gives the term (100x^100)/100, which simplifies to x^100. Add the constant of integration, C, to get F(x) = x^100 + C.
Step 4: Use the given condition F(1) = 101 to solve for the constant C. Substitute x = 1 into F(x) = x^100 + C, which gives 101 = (1)^100 + C. Simplify to find C = 101 - 1 = 100.
Step 5: Substitute the value of C back into the antiderivative. The final expression for F(x) is F(x) = x^100 + 100.
