Xiao Fang designed a calculation program with computer. The input and output data are as follows: input 1 2 3 4 5 … Output So, when Enter 1 2 3 4 5 … Output 1 in 2, 4 in 17, 5 in 26 What is the output data when input 8?
8 out of 65
The denominator is the square of the numerator + 1. The numerator is the number entered
Without using a calculator, compare the size of √ 2 and 3 ^ √ 3
Take these two numbers together to the sixth power,
that
(√2)^6=2^3=8
And (# 179; √ 3) ^ 6 = 3 ^ 2 = 9
therefore
(√2)^6 < (³√3)^6
So of course
√2 < ³√3
Can you compare the size of 2 + √ 5 and √ 3 + √ 6 without a calculator? Please explain why
(2 + √ 5) square = = 9 + 4 √ 5
(√ 3 + √ 6) square = = 9 + 4 √ 9 obviously √ 3 + √ 6 is greater than (2 + √ 5)
What is the meaning of BV-2 * 2.5/pvc20-wc, CC in lighting plan
Two bv-2.5mm2 insulated conductors are laid through pvc20 plastic pipes along the roof and wall
WC: concealed laying along the wall
CC: concealed laying along the ceiling
If we use 8421BCD code to represent two decimal numbers, we need at least () 0 and 1 code
WENWEN
8421 code is to expand the decimal number 8421 into binary
0＝0000 1＝0001 2＝0010 3＝0011 4＝0100 5＝0101 6＝0110 7＝0111 8＝1000 9＝1001
One decimal number is represented by 4-bit binary, so two decimal numbers naturally need 8-bit 0 and 1 code
The representation of zero is unique. Is it a () code in machine number?
As the title!
Original code, complement code, shift code, inverse code
Let's take it. Any score of 3qq is OK. First, everyone likes this. Second, maybe I'll ask you one day. Third, encourage me. The answer is complement. I've studied the meaning of the existence of the original anti complement, but you don't have any score. Can you recover the score? One of the reasons for the existence of complement is to unify positive 0 and negative 0 and positive zero
If the true value of 10110010b is - 4dh, the representation of the number of machines is（
The original code of 4D is 1001101b, and - 4D is negative for each of the following
Computers process information in digital form. Is that right?
No. computer processing information can take many forms
Computers can directly process numbers, words, sounds, graphics, and other types of information?
It's not right
To process this information, you need to install the corresponding software
The first power of 3 + 1 = 4, the second power of 3 + 1 = 10, the third power of 3 + 1 = 28, the fourth power of 3 + 1 = 82 According to this rule, calculate the number of 3 to the power of 2011 + 1
The quintic power of 3 is 243 plus 1 is 244
The period is four, four cycles
4,0,8,2,
2011 divided by 4 = 502 remaining 3
It's eight
