a=√75+√48-√12=5√3+4√3-2√3=7√3
b=√108+√147+√192=6√3+7√3+8√3=21√3
mg=√(7√3×21√3)=√7²×3×3=21

a=√200+√50-2√18=10√2+5√2-6√2=9√2
b=√162+√338-√32=√162+√338-√32=9√2+13√2-4√2=18√2
mg=√(9√2×18√2)=√9²×2×2=18


a=(5 2/3-3,75+3/4)×(3/2)⁻¹ =(17/3-15/4+3/4)×(2/3) =
=(17/3-12/4)×(2/3) =8/3×2/3 =16/9

b=[0,08(3)]⁻¹+√116,64:2 7/10=12+10,8×10/27=12+108/27=12+4=16
0,08(3)=(83-8)/900=75/900=1/12
mg=√(16/9×16)=16/3=5,(3)


a=[√(√3-2)²+√(1-√3)²]×√1/0,25=(-√3+2-1+√3)×√4=2
b=(10√18-√72+6√8):√8=(30√2-6√2+12√2):2√2=36√2:2√2=18
mg=√2×18=√36=6
