The root sign is a symbol used to represent the root operation of a number or an algebra. If a? =b, then a is the n-th root of b or a is the 1/n power of b.

Draw a short diagonal line in the upper right corner of the middle of the grid, and then draw a middle diagonal line to the lower right continuously. For the same stroke, draw a long diagonal line to the upper right continuously, and then draw a horizontal line with moderate length near the top of the grid according to your own needs, which is not enough.

Extended data:

The number of roots or algebraic expressions are written in the area surrounded by the right side of the V-shaped part on the left side of the symbol and the lower part of a horizontal part above the symbol, and cannot be out of bounds. If the number of roots or algebraic expression is too long, the upper horizontal part must be extended to ensure the coverage of the root number or algebraic expression below.

Write the root number or formula: write n √~ on the left side of the symbol. When n=2 (square root), n can be ignored, but if it is a cubic root (cubic root), a quartic root, etc. , must write.
