Suppose a, b are relatively prime integers. (a) Show that gcd(8a, 8b) = 8. (b) Show that d = gcd(a + 3b, 3a + b) must be a factor of 8.

Find the GFC of 35n^2m of 21m^2n

Which term of the expansion of (x6 + 6)²⁰ contains 30 26 Term number contains 30

Let q(n) be the sum of the squares of the first n odd numbers. For example: q(0)  =  0 q(1)  =  12 q(2)  =  12 + 32 q(3)  =  12 + 32 + 52 q(4)  =  12 + 32 + 52 + 72   ⋮   What would be the closed-form expression for q(n), where n is any integer greater than or equal to 0? Your expression must work for any such n, not just those shown in the examples.
