Question

there are about 2.5x10^10 red blood cells in an average adult. About how many adults would it take to have a total of 1 googol red blood cells

Answer 1

It take
`{4* 10^(89)` adults to have a total of 1 googol red blood cells.

Explanation:

Consider the provided information.

1 googol is
`1* 10^(100)`

It is given that there are about
`2.5* 10^(10)` red blood cells in an average adult.

To find how many adults would it take to have a total of 1 googol red blood cells divide the 1 googol with
`2.5* 10^(10)` .

`(1* 10^(100))/(2.5* 10^(10))`

`(1* 10^(100-10))/(2.5)`

`(1* 10^(90))/(2.5)`

`(10* 10^(89))/(2.5)`

`{4* 10^(89)`

Hence it take
`{4* 10^(89)` adults to have a total of 1 googol red blood cells.

Answer 2

A googol is 10 raised to the power 100 i.e. 10¹⁰⁰

Number of RBCs in an average adult = 2.5x10¹⁰

Number of adults required for 1 googol red blood cells = 10¹⁰⁰ ÷ 2.5x10¹⁰

⇒ Number of adults required for 1 googol red blood cells = 10¹⁰¹ ÷ 25x10¹⁰

⇒ Number of adults required for 1 googol red blood cells = 100x10⁹⁹ ÷ 25x10¹⁰

⇒ Number of adults required for 1 googol red blood cells = 4x10⁸⁹

Hence, 4x10⁸⁹ adults are required to have a total of 1 googol red blood cells
