Question
Who among the following is credited with the discovery
of X-rays?Solution
Wilhelm Roentgen, a German physicist, discovered X-rays in 1895. This groundbreaking discovery has since revolutionized the fields of medicine and imaging, enabling the non-invasive observation of internal bodily structures.
x= √(4 × ∛(16 × √(4 × ∛(16 ×…… ∝)) ) )
What will come in place of (?) in the given expression.
(18 + 24 ÷ 6) × 2 - 5 = ?12.5% of 384 - 16.66% of 66 = √16 + √? + 22
420 ÷ 7 + 140 % of 20 + ? × 13 = 18 × 15
{(300 ÷ 15)% of 1500} ÷ 6 = ? + 120
- Simplify:
25% of [160% of (42 + 18) + 124] ÷ 66 × 150 - What will come in the place of question mark (?) in the given expression?
389 + 641 - ? = 180 X 2 What value should come in place of the question mark (?) in the following question?
468 × 4 − 350 ÷ 7 + 130
1404 ÷ 26 x 3 + 7 = ?2
