You can rewrite radical form expressions by putting the expression to the power of 1/n, n depending on the radical. For example: sqrt2 = 2^(1/2) or cuberoot4= 4^(1/3). Vice versa with rational exponent equations: 5^(1/2) = sqrt5 or 3^4/3 = cuberoot3^4

A certain bacteria culture grows at a rate of 18% everyday. There are currently 420 bacteria. How many bacteria will there be on

spayn [35]

In this question, it is given that

A certain bacteria culture grows at a rate of 18% everyday. There are currently 420 bacteria.

And we have to find number of bacterias on day *.

For that we use the following formula

$N(t) =N_{0} (1 +r)^t$

$N(0)= 420, r = 0.18 , and \ t = 8days$

Substituting these values in the formula, we will get

$N(8)= 420(1+0.18)^8
\\
N(8)=1579$

THerefore on day 8, number of bacterias are 1579.
