the first step is to deal with the negative exponents, which causes numbers to go to the other side of the fraction
8x^{-9}+(-3x^{-3}y^{-2})(\frac{5}{x^6y^{-2}})
goes to

now we can simplify the multiplied terms

Now that we have common bases, we can add the 2 fractions together to get

Answer:
Step-by-step explanation:
Indicates leg lengths of 1 and√3 and hypotenuse 2, the desired ratio is √3/2
The lowest common denominator for 15 and 12 will get in this way
15=3*5
12 = 3*4
LCM will be 3*4*5=12*5=60
Since it's the order you're working out, the order in which you pick the players play a huge role. Thus, this is a permutation question.
Since you're picking 9 people from 11 players, the formula goes like this:

different ways.
