Question

when a^2 is divided by 6 then _ is not remainder?
a. 1
b. 4
c. 3
d. 5​

Answer 1

Step-by-step explanation:

We know,

Remainder formula: Dividend = Quotient x Divisor + Remainder.

Let x=6q+3

Then, x2=(6q+3)2

=36q2+36q+9

=6(6q2+6q+1)+3

Thus, when x2 is divided by 6, then remainder =3.
