Our problem becomes 4x-1=3x+6 To solve this, we need to get all of the x's on one side, we are going to subtract 3x to do that. We end up with:
x-1=6
Now we just need to get rid of the -1 and we're home free. We get rid of that -1 we just add one
x=7
Any questions?
expression is equivalent to 
We apply exponential property
Multiply the outside exponent 1/2 with exponents inside the parenthesis


1/4 times 1/2 is 1/8
16 times 1/2 is 8
so expression becomes

So the answer is

The value of 5 in 5000 is 10 times the value of 5 in 500.
