a)√256 + {100= 16=10=26
b)11-{81*2+ {100*2=11-9{2+10{2=11-{2
c) {36*2+3{9*2+{4*2=6{2+9{2+2{2=17{2
d) 12+6-15=3
e)2+27=29???
f)5-3{10+3{10-18=-13
a) (√128+√50)*√2= √256 + √100 = 16+10 = 26
b) √121-√162+√200 = 11 - √2*81 + 20 = 11 - 9√2 + 20 = 31 - 9√2
c) √72+3√18+√8= √2*36 + 3√2*9 + √2*4= 6√2 + 9√2 + 2√2=17√2
d) (4√3+√12-√75)*√3= 12 + √36 - √225 = 12+6-15=3
e) (√2-3√3)do potegi 2= 2-27 = -25
f) (√5+3√2)*(√5-3√2)= 5-18=-13
co do b) nie jestem pewna
