(2+4+6+8+...+100) x (15x3-15x2-15)
=(2+4+6+8+....+100)x(15x(3-2-1))
=(2+4+6+8+...+100)x(15x0)
=(2+4+6+8+...+100)x0
=0
B=2^10*(2*3)^15+3^14*3*5*(2^2)^13/2^19*(2*3^2)^7*3-3^15*2^25
B=2^10*2^15*3^15+3^15+3^15*5*2^26/2^19*2^7*3^14**3-3^15*2^25
B=2^25*3^15+5*2*3^15*2^25/2*2^25*3^15-3^15*2^25
B=1*2^25*3^15+10*2^25*3^15/2*2^25*3^15-2^25*3^15
B=2^25*3^15*(1+10)/2^25*3^15*(2-1)=11/1=11
\(1-\left(\frac{2}{3}+\frac{1}{6}\right)=1-\left(\frac{4}{6}+\frac{1}{6}\right)=1-\frac{5}{6}=\frac{1}{6}\)
\(\frac{11}{5}:\frac{11}{2}=\frac{11}{5}\times\frac{2}{11}=\frac{2}{5}\)
\(\frac{3}{5}+\frac{2}{5}\times\frac{1}{6}=\frac{3}{5}+\frac{1}{15}=\frac{9}{15}+\frac{1}{15}=\frac{10}{15}=\frac{2}{3}\)
!!!
\(x-\left(\frac{5}{6}-x\right)=x-\frac{2}{3}\)
\(\Leftrightarrow x-\frac{5}{6}+x=x-\frac{2}{3}\)
\(\Leftrightarrow\left(x-x\right)+\frac{5}{6}=x-\frac{2}{3}\)
\(\Leftrightarrow0+\frac{5}{6}=x-\frac{2}{3}\)
\(\Leftrightarrow x-\frac{2}{3}=\frac{5}{6}\)
\(\Leftrightarrow x=\frac{5}{6}+\frac{2}{3}\)
\(\Leftrightarrow x=\frac{5}{6}+\frac{4}{6}\)
\(\Leftrightarrow x=\frac{3}{2}\)
\(3,56-\left|\left(\frac{3}{2}\right)^2:\left(\frac{-3}{6}\right)\right|\)
\(=3,56-\left|\frac{3^2}{2^2}:\left(\frac{-3}{6}\right)\right|\)
\(=3,56-\left|\frac{9}{4}.\frac{-6}{3}\right|\)
\(=3,56-\left|\frac{3}{2}.\left(-3\right)\right|\)
\(=3,56-\left|\frac{-1}{2}\right|\)
\(=3,56-\frac{1}{2}\)
\(=3,56-0,5\)
\(=3,06\)
