(3K)^0K^-3/K^6H^-9

Question

COULD YOU PLEASE HELP ME OUT TO SIMPLIFY THIS EXPRESSION

thank you so much

Answer 1

(3K)⁰K^-3         K^-3

----------- = -----------      because (3K)⁰ = 1, because ANY number to the 0 power is 1

  K⁶H^-9         K⁶H^-9

 

 

Now, whenever you have a negative power in a fraction, just switch it to the other side (top or bottom) and get rid of the minus sign.

 

So this becomes:

 

   H⁹             H⁹

---------  = --------  because of the rule for multiplying powers of the same number.

  K³K⁶          K⁹

 

So the answer is H⁹/K⁹
