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.
