C = \(\left(\frac{1}{2}-1\right)+\left(1-\frac{3}{4}\right)+\left(\frac{7}{8}-1\right)+......+\left(1-\frac{1023}{1024}\right)\) ) . tính c
Tính:
a, \(\frac{\left(\frac{3}{10}-\frac{4}{15}-\frac{7}{20}\right).\frac{5}{19}}{\left(\frac{1}{14}+\frac{1}{7}-\frac{-3}{35}\right).\frac{-4}{3}}\)
b, \(\left(\frac{1}{2}-1\right)+\left(1-\frac{3}{4}\right)+\left(\frac{7}{8}-1\right)+...+\left(1-\frac{1023}{1024}\right)\)
giải chi tiết giúp mk nha
tối nay mk cần
\(\left(\frac{1}{2}-1\right)+\left(1-\frac{3}{4}\right)+\left(\frac{7}{8}-1\right)+...+\left(1-\frac{1023}{1024}\right)\)
\(\left(\frac{1}{2}-1\right)+\left(1-\frac{3}{4}\right)+\left(\frac{7}{8}-1\right)+...+\left(1-\frac{1023}{1024}\right)\)
Tính: \(M=\frac{1}{2}+\frac{2}{4}+\frac{3}{8}+\frac{4}{16}+\frac{5}{32}+...+\frac{10}{1024}\)
1 Tính A = 3+32+33+.....32016
B= \(\frac{1}{2}\)+\(\frac{1}{4}\)+\(\frac{1}{8}\)+......\(\frac{1}{1024}\)
các bạn giúp mình giải bài nhé
tính \(-1-\frac{1}{2}-\frac{1}{4}-\frac{1}{8}-......-\frac{1}{1024}\)
Tính A= \(\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+...........+\frac{1}{512}+\frac{1}{1024}\)
Tính :
\(\frac{1}{2}-\frac{1}{4}-\frac{1}{8}-...-\frac{1}{1024}\)
