√289 + √49 + 121 =?
√2401 × (√2116 ÷ 23) × 21 ÷ 3 = ?
If (x + 1/x) = 5, then value of x3 + 1/x3 is:
1(1/2)+ 11(1/3) + 111(1/2) + 1111(1/3) + 11111(1/2) = ?
√ (122 + ? + 65) = 14
I. 8x² - 74x + 165 = 0
II. 15y² - 38y + 24 = 0
1555.5 + 1000.8 – 1354.3 = ? + 52
Simplify-
x + 3(y + x – 2) – (x + y).
(8 x 9) ÷ 5 + ?2 = 23.4
