and that's a question it's required toe. Simplify this expression. So as you can see the biz off, each power is the same, which is be. And there are combination off modification off these powers with the division or with the third power. So let's start by writing the common base B. Andi exponents, I'll start with minus two. It's alright. Minus two Now. The second export here is beatable. Minus three. Uh, this power is multiplied by the first power, so I have toe add explains So it's minus two plus minus three. So plus minus three on dhe. Now, this power here is a division with the previous two powers. So I have to subtract minus nine from the previous exponents. So it's minus minus nine. On this is B did the power off minus two, minus a three and plus nine. So now it's subject and add the numbers minds to my three is minus five minus five. Last night is for so it's B to the power off four and this is Di flying the solution off this question
