Hello, i have a question.
00:02
In this, i am to find the principal root of the following.
00:06
A is 484 under root.
00:10
Okay.
00:17
So this is 22.
00:21
This is first, second, 0 .81 under root.
00:29
This is 0 .9.
00:32
3rd, 144 by 225 under root.
00:39
So under root of 144 is 12, 225.
00:42
5 is 15 so 4 pi 5 and 4th okay this is irrational and rest all are rational but be cube root of 729 so 81 whole cube cube root so this should be 81 second minus 343 cube root so minus 7, cube raised to the power 1 by 3.
01:38
So minus 7, okay.
01:53
I think this is 9 raised to the power 3.
01:57
This has to be 9 equal to 9.
02:03
Third is 256 and it's cube root, sorry, 4th root.
02:12
So 4 raised to the power 4, raise to the power 1 by 4.
02:20
So answer should be 4 minus 81, 4th root.
02:27
So minus 81...
