Square root and cube roots.
Storyboard Text
Sure I'll be glad to help little bro.
Hey sis i need help understanding square roots can you help me.
Every number has a square root but there sometimes not going to be a whole number.
So every number has a square root but there sometimes not going to be a whole number so it will be a decimal.
So now in your calculator put the square root of 49 tell my what would it be.
Ok i got it its going to be 7.
Now tell me why is square root of 49 is 7.
I think its 7 because if you multiply 7 twice you'll get 49 this is a perfect square.
If you want. but not always you can round the whole number and find the closest number.
Right but not all square roots are going to be whole number remember that. So now do get it.
Yes but i want to know about decimals so if you try to find the square root of 50 do you put the whole number dot then write the rest.
So now little bro you'll be able to pass the test!
Thanks sis I'll let you know if i passed.
