Find the value of following polynomial at m = 1, n = -1 and p = 2: m³ + n³ + p³
Solution:
Given, the polynomial is m³ + n³ + p³
We have to find the value of the polynomial at m = 1, n = -1 and p = 2.
m³ = (1)³ = 1
n³ = (-1)³ = -1
p³ = (2)³ = 8
Now, m³ + n³ + p³ = 1 + (-1) + 8
= 1 - 1 + 8
= 8
Therefore, m³ + n³ + p³ = 8
✦ Try This: Find the value of following polynomial at m = -2, n = -1 and p = 2: m³ + n³ + p³
Given, the polynomial is m³ + n³ + p³
We have to find the value of the polynomial at m = -2, n = -1 and p = 2.
m³ = (-2)³ = -8
n³ = (-1)³ = -1
p³ = (2)³ = 8
Now, m³ + n³ + p³ = -8 + (-1) + 8
= 0 - 1
= -1
Therefore, m³ + n³ + p³ = -1
