Answer:
the exact form is
but the decimal form is 12.124 :)))
Step-by-step explanation:
There are more atoms in a human body because 7.5*10^18 is less than 7*10^27.
The standard form of this number is 7 * 10^1. The word form of this number is seventy.
One of the indicies rules is:
![{a}^{ \frac{m}{n} } = \sqrt[n]{ {a}^{m} }](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B%20%5Cfrac%7Bm%7D%7Bn%7D%20%7D%20%20%3D%20%20%5Csqrt%5Bn%5D%7B%20%7Ba%7D%5E%7Bm%7D%20%7D%20)
As you "root the bottom and power the top"
Using this format, we can see that 3rdrt8^x can be written as 8^x/3
By the way, 3rdrt8 means 3rd root of 8
5 times 3 is 15 so 3 people can get 5 block
