(ii)

4t34t^{3} - t2t^{2} + 6 if t = a

Answer

4a34a^{3} - a2a^{2} + 6

Explanation

To find the value of a polynomial at a given value of the variable, we substitute the specified value into the expression in place of the variable and simplify. For part (i), we substitute the number 1. For part (ii), we substitute the variable 'a' and write the resulting expression.
