What is the most indecent zodiac?

I come from a pig. I didn't know it at school before, but I wrote it down when I saw it online this time.

First, from the decimal point forward to the back, every two digits are divided into a paragraph.

For example, calculate √ 10.

3. 1 6 2 2 7 -

Generally speaking, only some commonly used numerical memory methods are memorized. For example, 19* 19=36 1, then the square root of 36 1 is 19.

But often the values are not so complete, so you have to use a calculator. Actually, manual work can also be counted. For example, to calculate the square root of 20, we first know that 4 * 4 = 16 and 5 * 5 = 25, then the square root of 20 must be 4 points. Then calculate how much 4.5*4.5 equals, compare it with 20, and then determine the next one. It's troublesome, but it's the only way. Calculator works according to this principle, but it is very fast.

I don't know if you went to high school, but it is ok to use images. You draw a power function image and then take the derivative, and you will know it at a glance.
