Question
( 15.25×15.25×15.25+24.75×24.75×24.75) /
(15.25×15.25-15.25×24.75+24.75×24.75)Solution
Let a = 15.25 and b = 24.75. So, (a3+b3) / (a2-ab+b2) As we know that - a3+b3 = (a+b) (a2-ab+b2). =(a+b) (a2-ab+b2) / (a2-ab+b2). The term (a2-ab+b2) cancel out and leave- =(a+b) =15.25+24.75 =40.
What will come in the place of question mark (?) in the given expression?
(63 - ?) ÷ 5 + √625 = 19 X (9 - 6)
- What will come in place of (?), in the given expression.
(4² + 6²) × 2 = ? What will come in the place of question mark (?) in the given expression?
(40/25) X 80 - ? = 45% of 300 - 5525.6% of 250 + √? = 119
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
Simplify the expression:
(5x + 15) / (x² + 3x)
What will come in the place of question mark (?) in the given expression?Â
435 ÷ 29 X 792 ÷ 44 = √(? + 14) + 35 + 221 ÷ 17
...192.251 + 326.233 + 125.021 + 19.273 = ?
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
