Answer:1/2x+2
Step-by-step explanation:
Answer:
3 * 10^3 in scientific notation.
3,000 in standard notation.
Step-by-step explanation:
We divide:
3.9 *10^5 / 1.3 * 10^2
= ( 3.9/1.3) * (10^5 / 10^2)
= 3 * 10(5-2)
= 3 * 10^3.
This equals 3 * 1,000 = 3000.
I assume the equation is

then let
.


The right side is real-valued and positive, and only on the left side do we have an imaginary term, which tells us

Then




but again we omit the negative solution, so that

41 bc it is prime and the ones is 3 less than the 10s
