(15 2\3 - 7 1\2 ):1 1\2=

2*(1\3 do potęgi 2 )+3*(1\2 do potęgi 3 ) PLIS NA POMOC POTRZEBNE NA JUTRO JAK COŚ TO NIE PISZCIE SAMYCH WYNIKÓ TYLKO CAŁE DZAŁANIE HHHHHHHHHHHHHHEEEEEEEEEEEEEEEEEEEEEEELLLLLLLLLLLLLLLPpppppppppp

Answer 1

(31/2 + 11/2) * 3 = 42/2 *3= 126/2=63

 

( 22/3- 4/5) *1 * 3/7= ( 110/ 15 - 20/ 15) * 3/7 = 90/15* 3/7 = 6* 3/7= 18/7

 

( 15* 2/3 - 71/2) :3* 1/2= ( 30/3- 71/2) :3/2= ( 60/6- 213/6)* 3/2+ -153* 2/3= - 306/18= - 17

 

2*( 1/3^2) + (3* 1/3^3)= 2*1/9 + 3* 1/8 = 2/9+3/8= 16/72+27/72= 43/72

Answer 2

(3 1/2+1 1/2)* 3 = 5*3= 15

 

(2 2/3-4/5)*1 3/7 = (2 10/15 - 12/15)* 10/7 = (1 25/15 - 12/15)* 10/7= 1 13/15 * 10/7 = 28/15 * 10/7 = 4/3 * 2/1 = 8/3 = 2 2/3 

 

 
(15 2/3 - 7 1/2): 1 1/2= (15 4/6 - 7 3/6) : 3/2 = 8 1/6 * 2/3 = 49/6 * 2/3 = 49/9 = 5 4/9 

2*(1/3 ^2) + 3*(1/2 ^3) = 2 * 1/9 + 3* 1/8 = 2/9 + 3/8 = 16/72 + 27/72= 43/72
