Question
If a + b + c = 0, then what is the value of
a3Â + b3Â + c3Â - 3abc?Solution
We know that, a3Â + b3Â + c3Â - 3abc = (a + b + c)(a2Â + b2Â + c2Â - bc - ab - ac) So, a3Â + b3Â + c3Â - 3abc = 0 X (a2Â + b2Â + c2Â - bc - ab - ac) [Since, a + b + c = 0]
√324 + √576 = ?/ √9
13 X √? + 256 ÷ 4 = 30% of 900 - 50
40% are the passing marks. A student gets 250 marks yet fails by 38 marks. What is the maximum marks?
What will come in the place of question mark (?) in the given expression?
(555 + 385 - 535) ÷ 15 X ? = 36 X 30
1231 + 1312 + 2113 – 3211 = ?
What will come in the place of question mark (?) in the given expression?
(144 × 16 ÷ 12) × 6 = ?Â
((9.77)0- 〖(0.1)〗(-1))/(〖(6/24 )〗(-1) ×(3/2)3+ 〖((-2)/6)〗(-1) ) = ?
...Find the HCF of 15x2 + 8x – 12, 3x² + x – 2, 3x² - 2x, 9x² - 12x + 4
