a) Số đó là: MMI=2001

b) Số đố là: XXVIII=28

NHỚ CHỌN MÌNH NHA

Bài 2: 

Áp dụng tính chất của dãy tỉ số bằng nhau,ta được

\(\dfrac{a}{2}=\dfrac{b}{3}=\dfrac{c}{4}=\dfrac{a+b+c}{2+3+4}=\dfrac{45}{9}=5\)

Do đó: a=10; b=15;c=20

\(2S=3^{31}-1=3^{28}.3^3-1=\left(...1\right).27-1=\left(.....7\right)-1=\left(...6\right)\)

\(\Rightarrow S=\left(...3\right)\)

Tận cùng bằng 3 nhé e

3^0 có tận cùng là 1.

3^1 có tận cùng là 3.

3^2 có tận cùng là 9.

3^3 có tận cùng là 7.

3^4 có tận cùng là 1.

................................

3S = ( 3^1+3^2+3^3+......+3^31 )

3S-S = ( 3^1+3^2+3^3+......+3^31 ) - ( 3^0+3^1+3^2+......+3^30 )

2S = 2^31-1

2^31 có tận cùng là 1. ( theo như công thức đã nêu trên )

=> 2S có tận cùng là 0.

2S-S = 2S : 2

=> S có tận cùng là 5 vì ....0 : 2 bằng 5.
