Answer 1

a)
a=3^3 • 5^2 - 3^3 = 3^3(5^2 - 1) = 3^3 • 24 = 3^4 • 2^3
b=3^5 - 3^4 = 3^4(3-1) = 2 • 3^4
cmmdc=2 • 3^4 = 162
b)
a=16^2(16-1) = 2^4 • 3 • 5
b=14^2(1+14) = 14^2 • 15 = 2^2 • 3 • 5 • 7^2
cmmdc=2^2 • 3 • 5 = 60
c)
a=20^2(1+20) = 20^2 • 21 = 2^4 • 3 • 5^2 • 7
b=5•[7^2(35-3)] = 5 • 7^2 • 2^5
cmmdc=2^4 • 5 • 7 = 560
d)
a=64+32=96=2^5 • 3
b=16+128=144=2^4 • 3^2
cmmdc=2^4 • 3 = 48
