Answer
View full question & answer→1. (c) In the given expression
$56 t^3+12 t^2+6 t+16 s^2+2 s+106$, the term which contains 6 is 6t. Therefore, 6 is the coefficient of t.
2. Factors of $56 t^3$ are $56, t, t$ and $t$.
3. (d) Since, the given expression has more than three variables. Thus, it is called polynomial.
4. In the given expression, there are not any term which contains same algebraic expression.
Hence, there are not any like term in the given algebraic expression.
Hence, Riya is not correct.
