Answer:
B.
Step-by-step explanation:
So B is the correct answer.
Answer: What is the question????
First you need to find the common denominator. Think of a number that both 2 and 5 can go in to evenly. 10 is the best number, so, make both denominators 10. What you do to the bottom, you must do to the top.
Now your equation is 5/10-2/10
Your answer is 3/10
2x1=2
2+1=3/2
=3/2 is the answer
Anything to the zeroth power is 1, so the answer is just 1.
