a) x - 920 = 99920

    x          = 99920 + 920

    x          = 100840

b) x + 90 - (-29) = 10020

    x + 90          = 10020 + (-21)

    x + 90          =  9991

    x                 =  9991 - 90

    x                 =  9901

c)  99 - x = 90

           x = 99 - 90

           x = 9

d) -x + 93 = -1

    -x        = -1 - 93

    -x        = -94

a, x - 920 = 99920                                                            c, 99 - x = 90

x = 99920 + 920                                                                           x = 99 - 90 

x = 100840                                                                                    x = 9 

             Vậy x = 100840                                          Vậy x = 9 

b,x + 90 - (-29) = 100020                                                      

x + 90 = 100020 + ( -29 )

x + 90 = 99991

x =   99991 - 90 

x =  99901

Vậy x = 99901

Bạn Tuấn Anh ko bik thì thôi đừng viết bậy

Ta có : \(3.2^x=2^8+2^9\) 

\(\Rightarrow3.2^x=2^8.\left(1+2\right)\)

\(\Rightarrow3.2^x=2^8.3\)

\(\Rightarrow2^x=2^8\)

\(\Rightarrow x=8\) 

Vậy \(x=8\)

\(E=\frac{1}{1.101}+\frac{1}{2.102}+\frac{1}{3.103}+...+\frac{1}{10.110}\)

=> \(100.E=\frac{100}{1.101}+\frac{100}{2.102}+\frac{100}{3.103}+...+\frac{100}{10.110}\)

\(=\frac{101-1}{1.101}+\frac{102-2}{2.102}+\frac{103-3}{3.103}+...+\frac{110-10}{10.110}\)

\(=1-\frac{1}{101}+\frac{1}{2}-\frac{1}{102}+\frac{1}{3}-\frac{1}{103}+...+\frac{1}{10}-\frac{1}{110}\)

\(=\left(1+\frac{1}{2}+\frac{1}{3}+...+\frac{1}{10}\right)-\left(\frac{1}{101}+\frac{1}{102}+\frac{1}{103}+...+\frac{1}{110}\right)\)

\(F=\frac{1}{1.11}+\frac{1}{2.12}+\frac{1}{3.13}+...+\frac{1}{100.110}\)

=> \(10F=\frac{10}{1.11}+\frac{10}{2.12}+\frac{10}{3.13}+...+\frac{10}{100.110}\)

\(=\frac{11-1}{1.11}+\frac{12-2}{2.12}+\frac{13-3}{3.13}+...+\frac{110-100}{100.110}\)

\(=1-\frac{1}{11}+\frac{1}{2}-\frac{1}{12}+\frac{1}{3}-\frac{1}{13}+...+\frac{1}{100}-\frac{1}{110}\)

\(=\left(1+\frac{1}{2}+\frac{1}{3}+...+\frac{1}{10}\right)+\left(-\frac{1}{11}+\frac{1}{11}\right)+\left(-\frac{1}{12}+\frac{1}{12}\right)+...+\left(-\frac{1}{100}+\frac{1}{100}\right)\)

\(-\left(\frac{1}{101}+\frac{1}{102}+...+\frac{1}{110}\right)\)

\(=\left(1+\frac{1}{2}+\frac{1}{3}+...+\frac{1}{10}\right)-\left(\frac{1}{101}+\frac{1}{102}+...+\frac{1}{110}\right)=100E\)

=> 10 F = 100 E

=> \(\frac{E}{F}=\frac{10}{100}=\frac{1}{10}\)
