Question

p(t) = 4t^4 + 5t^3 - t^2 at t = a
​

Answer 1

$p(t) = {4t}^{4} + {5t}^{3} - {t}^{2} at \: t = a$

$So, \: 4 ({a})^{4} + 5 ({a})^{3} - ({a})^{2}$

$= {4a}^{4} + {5a}^{3} - {a}^{2}$

hope it helps u....!!

Answer 2

$\bigstar$ Question:

• Find p(a) where p(t) = 4t⁴ + 5t³ - t² where t = a

$\bigstar$To find:

• Find p(a) where t = a

$\bigstar$ Solution:

p(t) = 4t⁴ + 5t³ - t²

Now, since t = a

$\therefore$ p(a) = 4a⁴ + 5a³ - a²

(Substituting the value of t in p(t)

$\bigstar$Answer:

• Therefore, the answer is 4a⁴ + 5a³ - a²
