Which of the following shows the true solution to the logarithmic equation below? log4[log4(2x)]=1

128

The log is base 4. To undo the log, we raise both sides as exponents and the base will be 4.

So log(4,y) = 1 turns into y = 4^1 and it becomes y = 4

Replace y with log(4,2x) and we end up with log(4,2x) = 4

Repeat the step of raising both sides as exponents to get 2x = 4^4 leading to 2x = 256

The last step is to divide both sides by 2, which is why the answer is x = 128.

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
