1,2,3 These 3 terms each equal 1

 

4,5,8 These 5 terms each equal 2

 

9,10,15 These 7 terms each equal 3

 

16,17,24 These 9 terms each equal 4

 

25,26,29 These 5 terms each equal 5

 

Thus, the sum is (5×5)+(9×4)+(7×3)+(5×2)+(3×1)=95

Hey there, Guest!

 

So I just wrote out all the square roots:

 

1+2+3+4+5+6+7+8+9+1011+12+13+14+15+16+17+18+19+20+21+22+23+24+25+26+27+28+29

 

It's probably not the smartest idea, but it works.

Then I simplified all the possible squares.

 

15+110+13+14+15+17+19+62+21+22+23+26+29+63+35+36+37

 

Then you can simplify that into a decimal and you get 110.61.

 

And yes, I used a calculator for the last part, because who wants to do that by hand?

Not me, haha.

 

Hope this helped! :)
