Answer:

[tex]P(t) = 1161(9)^{t}[/tex]

Step-by-step explanation:

Given

[tex]P(t) = 43(3)^{2t+3}[/tex]

Required

Write in form of [tex]P(t) =ab^t[/tex]

[tex]P(t) = 43(3)^{2t+3}[/tex]

Apply law of indices:

[tex]P(t) = 43(3)^{2t}*3^3}[/tex]

Reorder

[tex]P(t) = 43*3^3*(3)^{2t}[/tex]

Express [tex]3^3[/tex] at 27

[tex]P(t) = 43*27*(3)^{2t}[/tex]

[tex]P(t) = 1161*(3)^{2t}[/tex]

Rewrite as:

[tex]P(t) = 1161*(3^2)^{t}[/tex]

Express [tex]3^2[/tex] as 9

[tex]P(t) = 1161*(9)^{t}[/tex]

[tex]P(t) = 1161(9)^{t}[/tex]
