Hard algebra problem

[frail flume]

I might be wrong with the problem, because was on a math contest, but how would you calculate it, I tried using trinomial squared by letting the root be equal to a variable but I’m lost

Is that all that's given?

Left-to-right is standard for everything except exponents: a ^ b ^ c is evaluated from right-to-left—a ^ (b ^ c)

This is common in computer programing. For instance, doing symbolic division I often write things as expr / x / 2 rather than expr / (x * 2) or (expr / x) / 2—you can imagine for the last one that expr is quite long and it could be hard to see where the parentheses start and stop. Like I might write factor((4x^2 - 8 * x + 4) / (x - 1) / 4) rather than factor(((4x^2 - 8 * x + 4) / (x - 1)) / 4). In my opinion the first is slightly easier for a human to read.

Yes

Maybe the g wasn’t there

I can’t remember
