Find the value of:

{5.66×5.66-4.44×4.44 }/{2-.78}

+ (6.53 × 8.34 – 6.53 × 5.17 – 6.53 × 3.17)

Solution:

{5.66×5.66-4.44×4.44 }/{2-.78}

+ (6.53 × 8.34 – 6.53 × 5.17 – 6.53 × 3.17)

={(5.66)^2 -(4.44)^2 }/{2-.78}

+ 6.53 ( 8.34 – 5.17 – 3.17)

={(5.66 +4.44) (5.66-4.44) }/{1.22}

+ 6.53 × 0

={10.10×1.22}/1.22+0

=10.10=10.1
