0 Next let us learn about the power function. Power is 1

Nothing but 2

It just gives you m to the power n 3

So 2 raised to the power 3 is 2 cube which is 8 4

6 raise to the power 2 is 6 square which is 36 5

So 6

If you want to find out any power of any number 7

This is the power function you write power 8

And give it two inputs 9

m and n 10

It will raise m to the nth power 11

If you want to find out 12

6 square this is what we will write select power 6, 2 13

You want to find square of all the ages for some reason you can write 14

Age, power age comma 2. So where this can help you is 15

If you are into statistics and you want to find out standard deviation or variance 16

That is where 17

Squares and other 18

Similar types of calculations can be used 19

So this is how we use 20

Power 21

Let's go and write this 22

Select 23

Power age 24

Comma 2 25

Comma age From 26

Customer 27

Let us run this 28

You can see 29

we have age of 67. 67 square is 30

4489 31

31 square is 961 32

65 square is 4225 33

Those are all the functions that we will be covering 34

Apart from this there are some other mathematical functions also 35

Which are very specific 36

If someday you need to use some other function just go to Google you can find those or you can find 37

These functions in the 38

Postgres documentation also and we will be sharing the link of that documentation page 39

That webpage 40

Along with this lecture 41

That is all for mathematical functions 42

In the next section we will look at some other type of function
