I still didn't get the answer

3. anonymous

ok. show me what you did

4. MikeyMaximum

1st 5*5=25 2nd 15*15=225 3rd 25+225=250 4th 250*250=62,500

@MikeyMaximum, you started right, but your fourth step is not the right one $a^2+b^2=c^2$ $5^2+15^2=c^2\\ 25+225=c^2\\ 250 = c^2\\ c=\sqrt{250}\\ =$

9. MikeyMaximum

O... Ok

10. UnkleRhaukus

to simplify √250, first factor 250

11. UnkleRhaukus

do you know how to factor 250?

12. MikeyMaximum

Its B right?

13. UnkleRhaukus

im not up to that point yet

14. MikeyMaximum

o

15. UnkleRhaukus

250 = 25*10 right? now can you further factor 25? and 10?

16. MikeyMaximum

I didn't exactly learn that yet :P

17. UnkleRhaukus

what number when multiplied by it self makes 25?

18. MikeyMaximum

5

19. UnkleRhaukus

5*5 = 25 and 2*5 = 10 so 250 = 5*5 * 2*5 = 5^2 * 2*5 We have √250 = √5^2 * 2*5 = 5*√2*5= (calculator says) 15.8 , yeah B
