Compute the sum 1√100+√102+1√102+√104+1√104+√106+⋯+1√9998+√10000.Just give me a hint. Thank you!
Tell me if you need more help. :))
(a+b)(a-b) = a^2-b^2
=^._.^=
Also, welcome to web2.0calc :DDDD
TYSM, I got the answer 45. Also thanks for welcoming me.
YAYY. :))
(sqrt(100)-sqrt(102)+sqrt(102)-sqrt(104)...sqrt(9998)-sqrt(10000))/-2
Everything cancels out. :DDD
(10-100)/-2=45
+180
