- Ya?!What do you want robert?
- HEY ANDRE.
- yes?
- Can you help me with my square root and cube root homework?
- Come on now dear, help your little brother out.
- Fine!
- For example the cube root of 512 is 8 because 8x8x8=512,so find the number that is equal to 512 if you multiply it three times by it self.
- Yes!
- Ohh,so the answer would be...8?
- Find the cube root of 512.
- To find the square root of a number you need to find the X-number that is multiplied itself twice that equals to the number.
- Yes,that's correct!
- Now i understand cube root let's move on to square root.What is the square root of -81?
- Okay,so the square root of -81 is...-9?
- You can use it to compute distances.
- Andre,when will I use square root and cube root in real life?
- Thank You andre for helping me with my homework.
