If a person doesn't know that sqrt is 1^(1/2) probably (just probably...) that person would never need to use sqrt...

I disagree. One can use square roots to find the roots of quadratic equations (for example the equation for the velocity of a projectile) without needing to know that sqrt(x)=x^1/2.

I think you misunderstood

The point he or she was making was that a person that doesn't know that sqrt(x)=x^1/2 probably wouldn't be calculating the for example velocity of a projectile

[juanefren]

Exactly...
