Answer:
3 is correct answer
Step-by-step explanation:
root 2 and pi are irrational numbers
The least common multiple of 14 and 24 is 168.
The lights flash together every 168 minutes.
168 minutes = 2 hours 48 minutes.
If they flashed together at 8 AM, then they'll flash
together again at 10:48 AM.
We have two numbers say a, b. And a system of equations.
It looks a bit intimidating but it's actually very easy.
Instead of term a + b in the second equation we can say it's zero because the first equation describes a + b as being equal to 0.
So,
The above equation is not true therefore numbers a and b do not exists in the real number domain.
No solution.
Hope this helps.
