Răspuns:

Explicație pas cu pas:

a) ⁴⁾3/11 + ²⁾5/22 + 15/44 = (12+10+15)/44 = 37/44

b) ¹⁰⁰⁾7/10+¹⁰⁾3/100+5/1000 = (700+30+5)/1000 = 735/1000⁽⁵ = 147/200

c) 30/45⁽¹⁵+98/56⁽¹⁴+21/35⁽⁷ = ²⁰⁾2/3 + ¹⁵⁾7/4 + ¹²⁾3/5 = (40+105+36)/60 = 181/60

d) 15/75⁽¹⁵+35/25⁽⁵+24/40⁽⁸ = 1/5 + 7/5 + 3/5 = (1+7+3)/5 = 11/5

e) ³⁾3/32+⁴⁾5/24+⁶⁾7/16 = (9+20+42)/96 = 71/96

f) 6/13+16/26⁽²+35/65⁽⁵ = 6/13+8/13+7/13 = (6+8+7)/13 = 22/13

g) ²⁾7/10+5/100⁽⁵+3/20 = 14/20+1/20+3/20 = (14+1+3)/20 = 18/20⁽² = 9/10

h) 4/3+24/36⁽¹²+16/24⁽⁸ = 4/3+2/3+2/3 = (4+2+2)/3 = 8/3
