Chapter 4.5, Problem 45HP

To determine

To find : how many adults would it take to have a total 1 googol red blood cells.

Answer to Problem 45HP

Adults would it take to have a total 1 googol red blood cells is $0.4\times {10}^{90}$ .

Explanation of Solution

Given information :

There are about $2.5\times {10}^{10}$ red blood cells in the average adult and googol is $1\times {10}^{100}$

There are about $2.5\times {10}^{10}$ red blood cells in the average adult.

A google is $1\times {10}^{100}$

So, adults would it take to have a total 1 googol red blood cells is

  $\begin{array}{l}\frac{1\times {10}^{100}}{2.5\times {10}^{10}}\\ \frac{1}{2.5}\times \frac{{10}^{100}}{{10}^{10}}\\ 0.4\times {10}^{90}\end{array}$

Hence, adults would it take to have a total 1 googol red blood cells is $0.4\times {10}^{90}$ .
