If x=1+2+3, then x44x34x2+16x=?


Answer:

8

Step by Step Explanation:
  1. Given: x=1+2+3
    According to the question, we need to find the value of x=1+2+3
  2. x=1+2+3x1=2+3
    Taking the square on both sides
    x2+12x=2+3+2×2×3     [ Using (a+b)2=a2+b2+2ab]x22x4=26
  3. Again, taking the square on both sides
     x4+4x2+164x3+16x8x2=4×6     [(abc)2=a2+b2+c22ab+2bc2ca]x44x34x2+16x+16=24x44x34x2+16x=8
