1/2 to ułamek jedna druga
a (3) do takie małe 3 nad 2
proszę oblicz Oblicz

2√ 72 - ½√50 + √2³ =
=2√2·36 -½√2·25 +√2·√2·√2=
=2·6√2 -½·5√2 +2·2√2=
= 12√2 -2,5√2 +4√2=
=13,5√2
2√72-1/2+√2(3)= 2√(8x9) - 1/2 √(25x2) +√2(3)= 6√8 -1/2 x 5√2+√2= 6√(2x4) -1/2 x5√2 +√2= 12√2- 5/2√2 +√2= 12√2 - 5√2= 7√2 ;;;;;;;;;;
3√3+ 2√2= 3 (1/3) <---(ułamek do potęgi taki, nad liczbą) + 2 (1/2)= 1+1=2
