Alright, let's try to solve this problem.
00:04
That's what we want to do.
00:05
We want to get the square root of 160 times r to the power of 7, times s to the power of 9, times t to the power of 12.
00:17
All right, first we get this number.
00:19
We know that 160 is equals to 160 times 10.
00:27
And this is 16 is 4 to the power to the power.
00:30
Of 2, where 10 itself is just 2 times 5, and we cannot move the data out from the square roots.
00:40
Then we can write this term in this way.
00:44
It's equals 16 times 10.
00:48
R to the power of 7 is equals to r to the power of 6 times r...
