Question

64x²+81y²+144xy , when x=11 y=4/3 {in (a+b)² format}​

Answer 1

Answer:

10000.66 (Approximately)

Step-by-step explanation:

64x² + 81y² + 144xy

Here, x = 11 and y = 4/3

So,

64(11)² + 81(4/3)² + 144(11)(4/3)

64 × 121 + 81 × 16/9 + 144 × 44/3

64 × 121 + 81 × 1.78 + 144 × 14.67

7744 + 144.18 + 2112.48

7744 + 2256.66

10000.66
