Question

Hej moglby mi ktos zrobić zadanie 39. PILSSSS!!!!!

Answer 1

Zad 39
a)
(1/2)⁴ + (1 3/4)² = 1/16 + (7/4)² = 1/16 + 49/16 = 50/16 = 3 2/16 = 3 1/8
b)
(2/3)³ * (2,25)² = 8/27 * 5,0625 = 8/27 * 50625/10000 = 8/27 * 2025/400 =
 = 8/27 * 81/16 = 648/432 = 27/8 = 3 3/8
c)
∛1/27 + √1 13/36 = 1/3 + √49/36 = 1/3 + 7/6 = 2/6 + 7/6 = 9/6 = 1 3/6 = 1 1/2
d)
(3/4)⁻¹ - (2,7)° = 3/3 - 1 = 1 1/3 - 1 = 1/3
e)
√(2 - 1/25) - √(1 - 0,99) = √1 24/25 - √ 0,01 = √49/25 - 0,1 = 7/5 - 1/10 = 
 = 14/10 - 1/10 = 13/10 = 1 3/10 = 1,3
f)
(1 1/9)⁻¹ : (1 2/3)⁻² = (10/9)⁻¹ : (5/3)⁻² = 9/10 : 9/25 = 9/10 * 25/9 = 2,5
