Answer:
1.3x10^-6
Step-by-step explanation:
Use a calculator.
0.00065/5 will give you 0.00013 which can be written as 1.3x10^-4 and multiply that by 10^-2, you will add the exponents -4+-2 and get -6 as your new exponent, ending with 1.3x10^-6
The associative property allows you to change the <em>grouping</em> of addends or factors without changing the value of the expression.
You can use cross product to slove this equation.
