Xiao Ming designed a calculation program with a computer. The input and output data are shown in the table below Input: 1 2 3 4 5 Output: 1 / 2 2 / 5 3 / 10 4 / 17 5 / 26 When the input data is 10, how much data should be output?
1/2=1/(1^2+1)
2/5=2/(2^2+1)
The 10th number is 10 / (10 ^ 2 + 1) = 10 / 101
Xiao Ming compiled a computer calculation program, when input
Xiao Ming compiled a computer calculation program. When inputting any rational number, the result on the screen is always equal to the sum of the absolute value of the rational number and 2. If inputting - 2, what is the result? If inputting a certain number, what is the result? If inputting - 7, what is the number? Write out the process
1, if you enter - 2, display the sum of the absolute value of = rational numbers and 2 = | - 2 | + 2 = 4
2, the display result will not appear negative, should be + 7, then if you enter a number, the result is 7, then the absolute value of the number = 7-2 = 5, the number is ± 5
Xiao Ming designed a program about real number operation. When the input value of X is 2, what is the output value?
(enter x) --- (x ^ 2) --- (- 1)
-----(output)
The output value is 3
(enter x) --- (x ^ 2) --- (- 1)
2 2²=4 4-1=3
-----(output) 3
