1. 3√2 + √50
2.(√3-√5)(√3-√5)
3. √m √m squared (the last m is sqaured)
4. 3 √13/√3 (the / means over √3
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
1. 3√2 + √50
---
= 3*sqrt(2) + sqrt(25*2)
---
= 3*sqrt(2) + 5*sqtt(2)
---
= 8*sqrt(2)
===================================
2.(√3-√5)(√3-√5)
= 3 - 2*sqrt(15) + 5
----
= 8 - 2*sqrt(15)
===================================
3. √m √m squared (the last m is sqaured)
---
= sqrt(m)*sqrt(m^2)
---
= |m|*sqrt(m)
===================================
4. 3 √13/√3 (the / means over √3
-------------
= [3*sqrt(13))/sqrt(3)
---
= [3*sqrt(39))/3
---
= sqrt(39)
===========================
