[2 1/2 - 1 2/3 * (- 0,9)]/(0,37 * 10) = [2 1/2 - 5/3 * (- 9/10)]/3,7 =
= (2 1/2 + 1 * 3/2)/3,7 = (2 1/2 + 1 1/2)/3,7 = 4 : 3,7 = 4 : 37/10 =
= 4 * 10/37 = 40/37 = 1 3/37
2.
√(1/9) - √(1/100) = 1/3 - 1/10 = 10/30 - 3/30 = 7/30
3.
√44 = √(4 * 11) = 2√11

(3⁶)⁻² * 3¹⁰ = 3⁻¹² * 3¹⁰ = 3⁻¹²⁺¹⁰ = 3⁻² = (1/3)² = 1/9
5.
√200 - √50 = √(100 * 2) - √(25 * 2) = 10√2 - 5√2 = 5√2
