So here we have to simplify the following expression.
00:04
As you can see, all powers have the same base.
00:07
And first, there is the multiplication and there is division between these powers.
00:15
So let's first write the common base a.
00:21
And let's start with the minus 5.
00:24
So i'll write part of minus 5.
00:27
Now, the second expound that i will write is minus 9.
00:33
The 8th of minus 9 with the 8th of minus 5 there is a multiplication.
00:38
So since there's a multiplication between these two powers, i'll take it minus 9 to be, i add the minus 9 to the previous power, to the previous exponent.
00:48
So it's plus minus 9 and there's a multiplication between these two powers.
00:56
Now the third power, there's a division...
