The answer is 16 because (-2*-2*-2*-2= 16)
Answer:
![123,456,789 = 1.23456789\times 10^8](https://tex.z-dn.net/?f=123%2C456%2C789%20%3D%201.23456789%5Ctimes%2010%5E8)
Step-by-step explanation:
It is required to find the value of the missing exponent in the below value i.e.
![123,456,789 = 1.23456789\times 10^x](https://tex.z-dn.net/?f=123%2C456%2C789%20%3D%201.23456789%5Ctimes%2010%5Ex)
Let the exponent is x.
Any number can be written in the scientific notation as :
![N=a\times 10^b](https://tex.z-dn.net/?f=N%3Da%5Ctimes%2010%5Eb)
a is a real number
b is any integer
In this case, the decimal is applied before 8 numbers. It means that the value of x is 8.
3 log 2x = 4
==> log 2x = 4/3
==> 2x = 10^(4/3)
==> x = \frac{10^(4/3)}{2}
