Final answer:
To find the remainder when dividing x³+3x²+3x+1 by x+π, use polynomial long division or synthetic division to divide the polynomial and find the remainder, which is 4π³+3π²+3π+1.
Step-by-step explanation:
To find the remainder when dividing x³+3x²+3x+1 by x+π, we can use the Remainder Theorem.
The Remainder Theorem states that if we divide a polynomial by a linear divisor, the remainder is equal to the polynomial evaluated at the negation of the divisor.
In this case, the divisor is x+π, so the negation is -(x+π).
Plugging this into the polynomial, we get:
R(x) = (x³+3x²+3x+1)|-(x+π)
Using polynomial long division or synthetic division, we can divide the polynomial to find the remainder:
R(x) = 4π³+3π²+3π+1
