If an exponent is negative you need to switch it to the other side.

So it would be 54v¼•w⅔

__________

18v⅔•¹¹/³•x5/7

Then you need to simplify it. So you would do 54÷18 to get 3.

NOTE: when you are simplifying it's dividing, so the answer you get goes where the larger number is. So in this case the 3 is where the 54 was.

Hey,
We can see here 2 of the angles are equal and the third one is a right angle right?
That means it is an isosceles triangle since they have 2 equel angles and a right anlgle.

Another feature of the isosceles triangle is that 2 sides are equal.
We are given one side is 5.5 right?
So the side BC has to be 5.5 or the side AB has to be 5.5
In isosceles triangles the side opposite to the 90 degree angle is the hypotenuse.This means it is the longest angle.
So it has to be AB which is equal to 5.5 since BC is the hypotenuse.

Hope this helps,Happy New Year

Lynna [10]
The answer is 23

Explanation:
5•2= 10, 2•8=16, 2•2=4, 3•3=9
The new problem is 10+(16)/(4)+9
Then divide because that comes first in PEMDAS : (16)/(4)= (4)
Now add: 10+4+9= 23
The answer is 23
