Reversing Order Scale - Math formulae help needed

Can anyone help with a formula / equation to help with my problem?
I'm trying to do (reverse) the following..........
I know the Base Price to be 250
The no. of orders are 8
Each order increases at scale of 1.5
=250*(1.5^7) = 4271.48 total
Im trying (and failing) to come up with a formula to reverse the above equation to provide me with the the Base Price (assuming I now know the total, in addition to the no of orders and the scale)
i.e what formula would I use to get the Base Price, assuming I know know the total is 4271.48 (based on the same 8 orders and scale of 1.5)
I've attached a quick spreadsheet to help describe my problem!

Thank you in advance :-)
Try this one. Use - in power.
=B17*(1.5^-7)

Header "x-ms-throttle-limit-percentage" not coming in response

My application makes a lot of calls to the graph API to get the properties I need. It is impossible to reduce the number of requests in my case. And for this, I need to understand when the number of requests approaches the limit and that I need to stop doing them so as not to get 429)
The documentation says that the parameter "x-ms-throttle-limit-percentage" should come in the header when the number of requests approaches the limit from 0.8. As I understand it, 0.8 is a coefficient from 1, where 1 is the upper limit of the limit:
https://learn.microsoft.com/en-us/graph/throttling?view=graph-rest-1.0#regular-responses-requests
But I didn’t get this parameter in the header, although Retry-After with TooManyRequests.
How can I get this parameter in the response? Perhaps you need to specify additional parameters for this? Or set up Tenant for this?
Or is there another way to view throttle-limit?
Thanks in advance for your reply)
If you haven't got "x-ms-throttle-limit-percentage" parameter in header response, this means that you haven't consumed more than 0.8 of its limit, its mentioned in docs. please check the screenshot.
You can check service specific throttle limit ,please follow docs ,
We were curious to know, what service you were hitting ?

Can someone see what is wrong with this XIRR() computation in Google Sheets? (I have sent a request to Google ...)

Please review https://docs.google.com/spreadsheets/d/1cWIAdWylD5Mx8zP5gFwkSVkAYLwXuFopoH_9mi2tGWg/edit#gid=0. It contains some dates and corresponding investment amounts. My goal is to have XIRR() compute the rate of return. While it is obvious that the result must be negative, the cell C1, with the formula XIRR(B3:B16,A3:A16), produces a huge positive number.
Thanks in advance.
I just realized that I didn't provide a 3rd argument, rate_guess, in the original invocation of XIRR(). (Thanks to #player0 for prompting me). With rate_guess provided, the result is believable.

Minimum memory required for SUB operation using accumulator?

This question might not be best questioned here but here it goes.
So, would the minimum memory addresses required for a sub operation in a cpu using an accumulator be 1 or 2?
I would say 1, since you can subtract the same value and store it in the same address, but when I asked a friend, he told me that "you assume 2 values not 1. So you begin with 2 memory addresses.". Is that really a requirement, theoretically speaking? (Practically, I don' see why would I not be able to use only 1 memory address).
Thanks in advance.

What significance does the parameter "begin" of urls yotube?

For example:

when we advance the video (in some cases) the case that the youtube player sends the parameter begin ... but not the number of bytes, then what is?

Sorry for my english.
Thanx!
I believe it's the number of milliseconds from the start.
