It involves cultivating crops parallel to the contour lines of the land, forming natural barriers that slow down the flow of water and reduce soil erosion.
Determine the simplified value of the given mathematical expression.
What will come in the place of question mark (?) in the given expression?
? = 20% of 25% of 15% of 12000
166/? = √576 - 3.25
∛857375 + ∛91125 = ? + √6889
(√529 + 63 /8)% of 800 = ?% of 250
(92.03 + 117.98) ÷ 14.211 = 89.9 – 30.23% of ?
4/5 + 6/7 × 14/42 ÷ 24/35 = ?
If a nine-digit number 389x6378y is divisible by 72, then the value of √(6x + 7y) will be∶
25639 – 5252 – 3232 = ?
