## Why doesn't Maple simplify exponents....

Maple 2022

I am wondering why Maple simplifies (x^(1/3))^3 to x ,  but not (x^3)^(1/3) .
I even tried the surd function. I believe the surd function is for real number arguments, so it should simplify to x.

 (2)

 (3)
 > simplify(surd(x^3,3))
 (4)
 > simplify(surd(x,3)^3)

This is what happened.

Here is a link to the document to replicate this behavior.

I know there is a solution , if you look at the [graph](https://www.desmos.com/calculator/3n7uzwrak4).

I also tried fsolve, but you have to narrow down the solution interval to look for a solution, and use an equality instead of an inequality.

## How to find second solution of non-algeb...

Maple 2020

I want to solve the equation x^(1/x) =1.2
`solve(x^(1/x)=1.2)`

The output is 1.257734541376526421
How do i get the other solution, numerically.

Is it possible to restrict or stipulate the domain to look for roots over a specific interval, some rootfinding command over the real numbers.
I also tried `solve(x^(1/x)=1.2,AllSolutions,explicit)`
Wolfram immediately gives me the second solution. https://snipboard.io/Nqt74K.jpg https://snipboard.io/Nqt74K.jpg

## Physics updates is not updating correctl...

Maple 2020

When i enter  `Physics:-Version() `I see the output

`The "Physics Updates" version "859" is installed but is not active. The active version of Physics is within the library`

`   C:\Program Files\Maple 2020\lib\maple.mla, created 2020,  March 4, 20:36 hours`

I tried to install it using Maple Cloud. The installation is stuck as seen below. Also i deleted the text file in the toolbox 2020 folder, maybe in the hope of starting from scratch.

Can someone please explain what to do to manually add the physics update, step by step. I am not that computer savvy as some of the users appear in other posts , I did try reading some.
I tried to download the physics update manually but I keep ending up with the same maple worksheet that says you need to use maplecloud.

In case you cannot read the text in the image

## maple help only works once per session?...

Maple 2020

I notice that when I enter `?convert` or `?convertin`into the maple prompt, the help window opens once and then ceases to function.

Update. It seems that the problem is not restricted to a specific command, this occurs for any command. To replicate, open help using F1, exit maple help, then open help again using F1. Maple help won't open again. I have to do a hard exit to get it to work again.
