Question

Sa mă ajute cineva va rog.​

Answer 1

a) a = (2/3 + 3/4 x 5/6) : 31/12

a = (⁸⁾2/3 + ³⁾5/8) : 31/12

a = (16/24 + 15/24) : 31/12

a = 31/24 x 12/31

a = 1/2

b = 3/V2 : (5V2 - 3/2 x 2V2)

b = 3V2/2 : (5V2 - 3V2)

b = 3V2/2 : 2V2

b = 3V2/2 x 1/2V2

b = 3/4

b) N = V(2x1/2 + 4x3/4)/2

N = V(1 + 3)/2

N = V4/2

N = 2/2
N = 1 este numar natural

Answer 2

Răspuns:

Explicație pas cu pas:

a) a = (2/3 + 3/4 x 5/6) : 31/12

a = (⁸⁾2/3 + ³⁾5/8) : 31/12

a = (16/24 + 15/24) : 31/12

a = 31/24 x 12/31

a = 1/2

b = 3/√2 : (5√2 - 3/2 x 2√2)

b = 3√2/2 : (5√2 - 3√2)

b = 3√2/2 : 2√2

b = 3√2/2 x 1/2√2

b = 3/4

b) N = √(2x1/2 + 4x3/4)/2

N = √(1 + 3)/2

N = √4/2

N = 2/2

N = 1 este numar natural
