When 70000 is written as 7.0 times (10^n), what is the value of n

Talking about right and left always confuses me.

If it is a big number the power is positive.

If it is a little number (less than 1) then the power is negative.

Easy Peazy

70,000 is definitiely a big number!

You have to move the decimal point 4 places to the right in 7.0 to get 70000, so n is 4.  That is 70000 can be written as 7.0x10⁴
