How Fast Can You Solve It? - Square Root Problem

[@ilovee271]

Literally solved it in my head in five seconds

[@MathMatrixUSA]

Good Job!

[@ilovee271]

@MathMatrixUSA thanks! I'm currently procrastinating from learning for my math olympiad..

[@fmax0]

Did you really solve it in your head in five seconds without knowing the answer before? That sounds impossible to me! 😮😮😮

[@ilovee271]

​@@fmax0 Well, I saw 49 appears twice, so I treated it as x, and 50 is x + 1, so you get (x²+x+x+1)^0.5, which is (x²+2x+1)^0.5, so the term inside the root is just (x+1)², but the root cancels it out, so it's just x+1 which is 50

[@MathMatrixUSA]

@AmitYellin WowGood luck with your olympiad! I'm sure you will do great!

I did it in a different way I saw that 49²+49+50 is like x²+x+x+1 So what we have is (x²+2x+1)½ = [(x+1)(x+1)]½ and (x+1)²½ = x+1

[@mikoujorio8200]

[(49)^2] + 49 +50=[(49)^2]+49+ 49+1= (49)^2+[49+49]+1 = (49)^2 + [2×49×1] + [(1)^2] = (a+b)^2= (49+1)^2 => [(49+1)^2]^1/2= 49+1=50

[@lokith8660]

ahh i did 49(49+ 1) + 50 = 49(50) + 50 = 50(49+1) = root(50x50) = 50

[@Kyanzes]

I did it this way as well.

Nice! Keep it up!

[@MathMatrixUSA]

Thank you so much!

[@shubham-ek8nr]

i used (a+b)² and i got my answer in 7 seconds

[@MathMatrixUSA]

Awesome!

[@adgf1x]

=>{49(49+1)+50}^1/2={50(49+1}^1/2=(50×50)^1/2=50 ans

[@agggg007]

I use Vedic Maths and solved it in 5 to 10 seconds 😅❤

[@pointlesspress]

It's just maths bro there is no such thing as Vedic math, Bible math or kuran math. And you can't guess you solving time.
