x=0.27

Step-by-step explanation:

We are given the equation;

The first step is to add 4.2 on both sides of the equation;

The next step will be to divide both sides of the equation by 1.2;

Next we take natural logs on both sides of the equation;

Finally, we divide both sides by 4*ln10 and simplify to determine x;

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
