\(\frac{10^3+2.5^3+5^3}{55}=\frac{1000+2.125+125}{55}=\frac{1375}{55}=25\)
chìu mk lm nha
Giờ mk có việc rồi
Nhớ tick cho mk nha !!!!!
\(\frac{10^3+2.5^3+5^3}{55}\)
\(\frac{10^3+2.5^3+5^3}{55}\)
tính:
\(b.\dfrac{10^3+2.5^3+5^3}{55}\)
helpppp me! mk sắp phải nọp rùi huhu
\(\dfrac{10^3+2.5^3+5^3}{55}\)
\(\dfrac{10^3+2.5^3+5^3}{55}\)
\(\dfrac{10^3+2.5^3+5^3}{55}-\dfrac{4^6.9^5+6^9.120}{8^4.3^{12}-6^{11}}\)
Tìm x , biết \(\frac{x+2}{327}+\frac{x+3}{326}+\frac{x+4}{325}+\frac{x+5}{324}+\frac{x+349}{5}=0\)
giúp mk vs
bài 1 tìm x
a) \(\frac{1}{20}-\left(x-\frac{8}{5}\right)=\frac{1}{10}\) b) /x-\(\frac{3}{2}\)/=\(\frac{4}{3}\) c) /x-\(\frac{1}{3}\)/= / \(-\frac{5}{2}\)/ -\(\left(\frac{1}{4}-\frac{2}{3}\right)\)
d)/x-\(\frac{5}{8}\)/-\(\frac{3}{4}\)=0 e) /2.x+ \(\frac{5}{6}\)/= /\(\frac{1}{5}-\frac{2}{3}\)/+\(\frac{-3}{4}\)
giúp mk vs mk đang cần gấp
tính
a)\(\left(1-\frac{1}{1+2}\right).\left(1-\frac{1}{1+2+3}\right).\left(1-\frac{1}{1+2+3+4}\right).....\left(1-\frac{1}{1+2+3+...+20}\right)\)
b)\(\frac{\left(1+2+3+...+100\right).\left(12.3,4-6,86\right)}{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+\frac{1}{5}+\frac{1}{6}}\)
c)(18.123+9.436.2+3.5310.6):1+4+7+...+100-410)
giúp mk vs mai mk kiểm tra rồi . ai đúng mk tick nha
