let x=3 and y=4. Find the value of the given capital letter.

N=x^2+2xy+y^2+1

Thank you

Replace x with 3 and y with 4. N=3^2+2^3^4+4^2+1

N=6+24+8+1
Now, just add.

^ means multiply, right? Because I use * as the sign. Just making sure.

N=x^2+2xy+y^2+1 ^ means power.

N= 3^2 + 2*3*4 + 4^2 + 1
= 9 + 24 + 16+1=50 check that.

Ohhh oops sorry, I didn't mean to make a mistake :0 But thanks for correcting me, bobpursley.

To find the value of the capital letter N, we need to substitute the given values of x and y into the expression for N and evaluate it.

Given:
x = 3
y = 4

Substituting the given values into the expression for N:
N = x^2 + 2xy + y^2 + 1
= (3)^2 + 2(3)(4) + (4)^2 + 1
= 9 + 24 + 16 + 1
= 50 + 17
= 67

Therefore, the value of the capital letter N is 67.
