Answer:

[tex]P(t) = 3810(1.0035)^{t}[/tex]

Step-by-step explanation:

Given:

[tex]P(t) = 3810(1.0005)^{7t}[/tex]             -----(1)

Simplifying [tex](1.0005)^{7t}[/tex]

From Law of indices, [tex]x^{mn} = (x^{m})^{n}[/tex]

[tex](1.0005)^{7t}[/tex] = [tex](1.0005^{7})^{t}[/tex]

When 1.0005 is raised to the 7th power, it is approximately 1.0035.

Substituting [tex](1.0005)^{7t} = (1.0035)^{t}[/tex] into equation(1)

[tex] P(t) = 3810(1.0035)^{t}[/tex]
