my name is richie
i have two questions and they are:
Please show me how you solved these problems
thank you!Hi Richie,
For problem 1 notice that 203 = 8000 so the middle prime is probably slightly smaller than 20.
For problem 2 the lcm of a and b is 144 = 24 x 32. Thus a = 2s x 3t and b = 2u x 3v for some integers s, t, u and v. Since a>or=2, either s is not zero or t is not zero. What does the fact that a and b are relatively prime tell you about s, t, u and v?Cheers,
