Answer:

Math will take over Ana's brain at 4.4 hours

Step-by-step explanation:

Exponential Grow

The population of the nanobots follows the equation

$p(t) = 5\cdot 2^t$

We must find the value of t such that the population of nanobots is 106 or more, that is

$5\cdot 2^t\geq 106$

We'll solve the equation

$5\cdot2^t= 106$

Dividing by 5

$2^t= 106/5=21.2$

Taking logarithms

$log(2^t)= log(21.2)$

By logarithms property

$t\cdot log(2)= log(21.2)$

Solving for t

$\displaystyle t=\frac{log21.2} {log2}$

$t=4.4 \ hours$

Math will take over Ana's brain at 4.4 hours
