Answer:

[tex]f(5)=2.048*10^{-7}[/tex]

Step-by-step explanation:

We have that [tex]f(x)=2x^{-10}[/tex], we want to find [tex]f(5)[/tex].

We can rewrite this function with positive index to get:

[tex]f(x)=\frac{2}{x^{10}}[/tex]

We need to substitute [tex]x=5[/tex] into the given function to get:

[tex]f(5)=\frac{2}{5^{10}}[/tex]

This implies that:

[tex]f(5)=\frac{2}{9765625}[/tex]

In scientific notation:

[tex]f(5)=2.048*10^{-7}[/tex]
