The correct answer is C
(5/8 of 480 - 30% of 420)² ÷ (√81 + 25% of 320) = ?
The value of ((0.27)2-(0.13)2) / (0.27 + 0.13) is:
{(522 – 482 ) ÷ (27 + 73)} × 35 = ?% of 17
?% of (√196) × 24 + 344 = 428
((67)32 × (67)-18/ ? = (67)⁸
Calculate the value of x2, if [(8 + 62) ÷ 4 of x + 2.5 × 5 = 42 + 20% of 10].
(392 + 427 + 226 – 325) ÷ (441 + 128 – 425) = ?
14 × 6 + 9 × 11 = (82 – 3) × ?
What is the value of (6 + 4) ×12/4 + 5 – 3?
Simplify the following expression.
(3-3 × 3 + 3 ÷ 3 + 3 × 5) × 2 of 5 + (2 + 2 ÷ 2 + 2 × 2 - 2)
