Which layer of the OSI model is used for providing

(18 × 9 ÷ 6) × 3 = ?

30% of 2200 +’?’ x 50 – 1020 = 11x 306 +  (√ 2250 ÷ 0.1)  

8⁹ ÷ 512 × (1/64) = (2³)^?

What will come in the place of question mark (?) in the given expression?

Find the simplified of the following expression:

Find the simplified value of the given expression:

15 of 4 ÷ 3 × 4² + √49 – 12

What will come in the place of question mark (?) in the given expression?

(96 - 59) X 6 + ?² = 136.5 X 4

135÷ 15 x 19 + 14807 = ? + √3249 - √9604

√1444 + √729 – √2116 = ?

20% of 550 × 25% of 80 = ?² × 22
