Question

evaluate 8.33 × 8.33 - 1.37 × 1.37 / 0.726 using suitable identities

Answer 1

Hey mate!

Here is yr answer.....


= 8.33 × 8.33 - 1.37 × 1.37 / 0.726

= (8.33)² - (1.37)² / 0.726

[a²-b² = (a+b)(a-b) ]

= (8.33+1.37)(8.33-1.37) / 0.726

= (9.7) (6.96) / 0.726

= 67.512 / 0.726

= 92.99

= 93


Hope it helps...
