10^8=100000000
100000000x6.71=671,000,000
(-5/3)•(-6/1)=(30/3)
(30/3) simplified is (10/1)
Answer:
x=2 y=2
Step-by-step explanation:
Irratonal numbers can't be written as a/b where a and b are integers and b≠0
so if it can be written in form a/b then it is not irrational

, it's rational
1/5 is rational

it's irrational because we can't simplify the square root further
6.3=6.3/1=63/100, rationanl
answer is
