Question 67 (f)

Find the value of the given polynomial at m = 1, n = -1 and p = 2

$m^{2} n^{2} + n^{2} p^{2} + p^{2} m^{2}$

Open in App

Solution

Given, m = 1, n = -1 and p = 2
So, putting m = 1, n = -1 and p = 2 in the given expression, we get
$m^{2} n^{2} + n^{2} p^{2} + p^{2} m^{2} = (1)^{2} (- 1)^{2} + (- 1)^{2} (2)^{2} + (2)^{2} (1)^{2} = 1 + 4 + 4 = 9$
