we need to pull out our caracas multiplication nunchucks and

reveal the imager behind the mask Well it may look

like we're supposed to divide five hundred by point Oh

five here But hold on there's got to be a

better way The problem is actually asking us to find

a number That man of mystery acts yet right there

that when divided into five hundred would move the decimal

to the left to the left from five hundred point

zero two zero point old five hundred Something got a

point Oh five We'll just forget solving the problem Algebraic

lee The easiest way to get from five hundred point

oh five is well to just figure this out Yeah

dividing five hundred by ten moves a decimal one place

to left You get fifty divided by ten squared It

moves it to places to left We had five And

then if we uh need four places to the left

well let's see What do we do there We've got

to move it from its original spot after the five

hundred point zero to get two point five so well

we have to divide five hundred by ten to the

fourth which in california is ten thousand years So that's

it is ten to the fourth one one two three

and then four places over to the left He at

that point oh five things ten thousand The answer is 00:01:34.583 --> [endTime] see you later
