Isn't it true that "irrational numbers are numbers that can not be opened "? Examples

This is not true. An irrational number is an infinite non-recurring decimal: it includes an algebraic expression with π, an infinite non-recurring decimal, and a number whose radix is infinite. For example:π,1.1010010001... ,√2, Etc.

1. You know that root 2 is an irrational number, and irrational numbers are infinite non-recurring decimals, so we can not write all the decimals of root 2, so small The root 2-1 is used to represent the decimal part of the root 2. Do you agree with Xiao Ming's representation? In fact, Xiao Ming's representation is reasonable, because the integer part of root 2 is 1. Subtract this number from its integer part, and the difference is the decimal part. Ask: Given 10+ root 3=x+y, where x is an integer and 0< y <1, find the opposite number of x-y.
2. Three times the root number 49 I through the calculator calculation found that it is a finite non-recurring decimal, not irrational number ah! Record the number that the calculator has calculated the root number 49 three times, bring it back in for calculation. Multiply it by the third power and it equals 9. Then isn't the root number 49 three times a rational number? Three times the root number 49 I found by calculator calculation it is a finite non-recurring decimal, not irrational number ah!
