Explanation for the correct option:
Given, 2+5-6-35+14-65
Apply formula (a-b)2=a2+b2-2ab
2+5-6-35+14-65=2+5-6-35+32+52-2×3×5=2+5-6-35+3-52=2+5-6-35+3-5=2+5-9-45=2+5-22+52-2×2×5=2+5-5-22=2+5-5-2=2
Hence, correct answer is option B
If 5x+72=32x−14, then x = ?
(a) 5
(b) -5
(c) 6
(d) -6
Using appropriate properties find:
(i) −23×35+52−35×16
(ii) 25×[−37]−16×32+114×25
Verify whether the given statement is true or false :
(i) (59÷13)÷52=59÷(13÷52)
(ii) {(−16)÷65}÷−910=(−16)÷{65÷−910}
(iii) (−35÷−1235)÷114=−35÷(−1235÷114)
Using appropriate properties, find:
i) −23×35+52−35×16
