a = sqrt(a) * sqrt(a); sqrt(a) * sqrt(a) / sqrt(a) = 15 => sqrt(a) = 15 => a=225

[@wastedontheyoung5585]

3 steps: simplify, solve for a, calculate.
done in less than 15 seconds

[@peace-now]

a/a^0.5 = 15
(square both sides.
a^2/a = 225
a = 225.

[@Tcrrxzz]

i just assumed a/sqrt(a) = (sqrt(a)*sqrt(a)/sqrt(a) = 15 and the sqrt(a) cancel out leaving sqrt(a) = 15 then square both sides, so a = 225

[@veijolalli326]

a/sqrt(a)=15 |*sqrt(a)
sqrt(a)=15
a=15^2= 225
-------------------
225/15=15

[@efrancy3382]

Dude a/sqrt(a)=sqrt(a)
So sqrt(a)=15
a=225(15*15)
I don't belive almost every one failed that was very very easy

[@RyanLewis-Johnson-wq6xs]

a/Sqrt[a]=15 a=225 225/Sqrt[225]=15 solution

click bait

[@RealQinnMalloryu4]

3^5(a ➖ 5a+3).

[@tuomollo]

So many unnecessary steps.

It’s in my head.
