my hobby is collecting comics. I started my hobby 2 years ago. My mother took me to the bookstore and bought some comics for me.I like reading comics for me. I like reading comics in my freetime because it helps me relax. I spend all lucky money to buy comics. I find this hobby interesting because comics make me funny and excited.

I hope that in the future, i'll have a big bookshelf of comics to read them.

Hơi ngắn, xin lỗi nhé !vui

I have many hobbies, but I like reading most. Books are always a good friend to me. It is a good way to improve my vocabularies by exposing many new words.I star to reading book when i in grade 3.my brother inspired me to do that.I usualy share my hobby with my friend and my english teacher.By reading, I get better at concentration because it requires me to focus on what I am reading for long periods. It also opens up the knowledge door for me. Reading books tell me about the world's history, let me see the structure of the brain, or bring me a story of Sherlock Holmes. I think reading is one of the most interesting indoors activity and I will keep this hobby forever.

24 - 16(x - 1/2) = 23

=> 16(x - 1/2) = 24 - 23

=> 16(x - 1/2) = 1

=> x - 1/2 = 1/16

=> x = 1/16 + 1/2

=> x = 9/16

27 tháng 12 2018

\(24-16(x-\frac{1}{2})=23\)

\(16(x-\frac{1}{2})=24-23\)

\(16(x-\frac{1}{2})=1\)

\(x-\frac{1}{2}=\frac{1}{16}\)

\(x=\frac{1}{16}+\frac{1}{2}\)

\(x=\frac{9}{16}\)

Vậy số thực x cần tìm là \(\frac{9}{16}\)

So sánh:\(10^{10}\) và \(48.50^5\)

Ta có:

\(10^{10}=10^{2.5}=\left(10^2\right)^5=100^5=\left(2.50\right)^5=2^5.50^5=32.50^5\)

Vì \(32.50^5< 48.50^5\)

\(\Rightarrow10^{10}< 48.50^5\)

Cần gì , giúp được giúp cho

3 tháng 11 2021

bạn cần giúp gì,mình giúp cho nè 

3:

a: 5^n luôn có chữ số tận cùng là 5 với mọi n là số tự nhiên

=>5^100 có chữ số tận cùng là 5

b: \(2^{4k}\) có chữ số tận cùng là 6 với mọi k là số tự nhiên

mà 100=4*25

nên 2^100 có chữ số tận cùng là 6

c: 2023 chia 2 dư 1

mà \(9^{2k+1}\) luôn có chữ số tận cùng là 9

nên \(9^{2023}\) có chữ số tận cùng là 9

d: 2023 chia 4 dư 3

\(7^{4k+3}\left(k\in N\right)\) luôn có chữ số tận cùng là 3

Do đó: \(7^{2023}\) có chữ số tận cùng là 3

Quy luật: 

+) các số có c/s tận cg là 0,1,5,6 nâng lên lũy thừa bậc nào (≠0) thì c/s tận cg vẫn là nó.

+) các số có tận cg là 2,4,8 nâng lên lt bậc 4n(n≠0) thì đều có c.s tận cg là 6.

+)các số có c/s tận cg là 3,7,9 nâng lên lt bậc 4n(n≠0)  thì đều có c/s tận cg là 1.

+) số có tận cg là 3 khi nâng lên lũy thừa bậc 4n+3 sẽ có tận cùng là 7

+) số có tận cg là 7 khi nâng lên lũy thừa bậc 4n+3 sẽ có tận cùng là 3

+) số có tận cg là 2 khi nâng lên lũy thừa bậc 4n+3 sẽ có tận cùng là 8

+) số có tận cg là 8 khi nâng lên lũy thừa bậc 4n+3 sẽ có tận cùng là 2

+) số có c/s tận cg là 0,1,4,5,6,9 khi nâng lên lũy thừa bậc 4n+3 thì c/s tận cg là chính nó

 

Bài 3: áp dụng quy luật bên trên

\(a.5^{100}=\overline{..5}\)     

\(b.2^{100}=2^{4.25}=\overline{..6}\)

\(c.9^{2023}=\overline{..9}\)  

\(d.7^{2023}=7^{4.505+3}=\overline{...3}\)

Bài 4:

\(A=17^{2008}-11^{2008}-3^{2008}\)

\(=\left(\overline{...7}\right)^{4.502}-\left(\overline{..1}\right)^{2008}-\left(\overline{..3}\right)^{4.502}\)

\(=\overline{..1}-\overline{...1}-\overline{...1}\)

\(=\overline{..9}\)

Bài 5:

\(M=17^{25}+24^4-13^{21}\)

\(=\left(\overline{..7}\right)^{4.6}.\left(\overline{..7}\right)+\left(\overline{..4}\right)^{4.1}-\left(\overline{..3}\right)^{4.5}.\left(\overline{..3}\right)\)

\(\overline{..1}.\overline{..7}+\overline{..6}-\overline{..1}.\overline{..3}\)

\(=\overline{...7}+\overline{..6}-\overline{..3}\)

\(=\overline{...0}\)

\(=>M⋮10\)
