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

Question

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

Thank you

Answer 1

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.

Answer 2

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

Answer 3

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.

Answer 4

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