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.

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.

10+Root 3=x+y, where x is an integer and 0< y <1
10+(√3-1)+1=X+y
Therefore, x=11, y=√3-1
X-y=11-(√3-1)=12-√3
Inverse number of x-y =-(12-√3)=√3-12

3 Under the root is an irrational number, and the irrational number is an infinite non-recurring decimal, so we can not write all the decimal part of 3 under the root. So Xiaoming uses 3-1 under the root to represent the decimal part of 3 under the root. Do you agree with the representation method of Xiaoming? In fact, Xiao Ming's representation is reasonable because the integer part 1 of 3 under the root number is subtracted from the integer part, and the difference is the decimal part.

Since 2> root number 3>1, Xiaoming is right to use root number 3-1 to indicate the decimal part of root number 3;
Because 3> root 5>2, x is an integer,0

Because 2> root number 3>1, Xiaoming uses root number 3-1 to indicate the decimal part of root number 3 is correct;
Because 3> root 5>2, x is an integer,0
