4g/cm^3
D = M/V
100g/25cm^3 = 4g/cm^3
First, add 84 to both sides, to isolate the exponential function.
Then, take the logarithm of both sides:
(2x+3)*log 5 = log 84
Solving for 2x+3, we get log 84 - log 5, and so
2x = -3 + log 84 - log 5. Dividing both sides by -3, we obtain the final answer:
-3 + log 84 - log 5
x = -----------------------------

Answer:
-2
Step-by-step explanation:
It' quite simple actually. Just remember that if the 10 is raised to a power that is positive move that amount of spaces to the right. Vice Versa, if it's negative, move to the left.
So in this case, the power is positive and it's a four so move fur spaces to the right. The answer would be 75,600
