a. C = 2 + 2² + 2³ + …….. +  2⁹⁹  + 2¹⁰⁰

= 2(1 +2 + 2²+ 2³+ 2⁴) +  2⁶(1 + 2 + 2²+ 2³+ 2⁴)+…+ (1 + 2 + 2²+ 2³+ 2⁴).2⁹⁶

 = 2 . 31 + 2⁶ . 31 + … + 2⁹⁶ . 31 = 31(2 + 2⁶ +…+2⁹⁶).

Vậy C chia hết cho 31

b. C = 2 + 2² + 2³ + …….. +  2⁹⁹  + 2¹⁰⁰ à 2C = 2² + 2³ + 2⁴ + …+ 2¹⁰⁰ + 2¹⁰¹

Ta có 2C – C = 2¹⁰¹ – 2 \(\Rightarrow\) 2¹⁰¹ = 2^2x-1 \(\Rightarrow\)2x – 1 = 101

\(\Rightarrow\) 2x = 102 

\(\Rightarrow x=51\)

nhớ đúng nhé

gọi tuổi em là :a

gọi tuổi anh là:ax6

ta có:       3x(a+3)= (ax6)+3

                3xa+9   = 6xa+3

                6xa+3 -3xa=9

               6xa-3xa+3=9

               3xa-3         =9

                3xa            =9-3

                3xa            =6

                a                =6:3

                a                = 2

vậy em hiện nay có 2 tuổi

tuổi anh là:      2x6=12(tuổi)

                              Đ/s:anh :  12 tuổi

                                       em:     2 tuổi

Khác thì với cùng thì ở đây có nghĩa là :

S₁+V₁ + that + S₂+ V₂

Đổi thành :

*) Nếu V₂ là các thì HT,HTTD, TL các loại....thì chuyển sang:

          S₂ + be + V_3/ed + toV

*) Nếu V₂ là các thì HTHT, QK các loại.....thì chuyển sang : 

         S₂ + be +V_3/ed + to have V_3/ed
