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.

  • algebra -

    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.
