Let a = 3*5*7 (mod 11) . What is the remainder when a is divided by 11?

We can simplify the given expression to: \(a = 105 (\mod 11)\)

 

This means that the remainder of a when divided by 11 is 105. 

 

However, we can simplify this furthur, because 105 can "go" into 11 9 times, with a final remainder of 6. 

 

This means that \(a = 6 (\mod 11)\)

 

Can you find the remainder from here?
