Congratulations, JB .....!!!

I don't know, rosala...the "Pisa Tower" may be more interesting, historically....

But, somehow, that "Tower of Pizzas" is holding my interest more at the present time...

LOL!!!

Nothing like a little "pizza humour" to get the day off on the right foot.....

Here's another way

log_√2(x + 4) ≤ 2

This says that

(√2)^2 ≥ x + 4    and, remembering that x + 4 > 0   ....so we have

2 ≥ x + 4          and      x + 4 > 0

-2 ≥ x               and      x > -4

So, the solution is

(-4, -2]  for x   ...note that -2 is included because (√2)^2  ≤ (-2 + 4)   ....

It depends upon the number and type of pizzas....

For instance, shrimp pizzas, being naturally thicker than pepperoni, require less  "stackage" to achieve a given height. Also, "thick crust" will require fewer than "thin crust." Please remember that your mileage may vary by manufacturer/preparer.

Now....if you just want to know the height of the "Pisa" Tower....it's about 55-56m., depending on whether we're measuring the "low" side or the "high" side.

Leaning Tower of Pizza.....

Leaning Tower of Pisa.....

There are two solutions on [0, 2pi]

One occurs at about (36.9, 2.4)  and the other at about (216.9, -2.4)

These solutions repeat on every 2pi interval

LOL!!!...are you sure it isn't a "cubed log??"

Hey, rosala....

I put this in Desmos as tan(x-y) = 1/(y + x^2).....it won't let me "capture" any  solutions, either...

Check out the big brain on BJ....!!!!

{don't forget.....  -5 is also a solution...}
