Answer:
No, Sorry.
Step-by-step explanation:
Since the bases are different, you'll have to change them even if they have a exponent or not. If you dunno how to make the denominators the same, just multiply the two by eachother.
Example) 1/2 - 3/4
Multiply 2 and 4 together, and then multiply the 4 to the one also. Multiply 2 to four and also to the 3.
The subtract from there.
and then Reduce (if needed.)
There are 13 clubs and 52 cards for a probability of 13/52= 1/4 for the first card being a club...
(cos Ф -cos Ф)² + (cos Ф + cos Ф)²
Firstly: (cos Ф -cos Ф)² = 0² = 0
Secondly :(cos Ф + cos Ф)² = (2cos Ф)². = 4. (cos Ф)² = 4cos² Ф
Mind you when you raise a cosine (or sin or tan...) to the n power, the n power should affect the cosine only and NOT the angle Ф
