Answer:
[tex]\frac{6247}{375000}[/tex]
Step-by-step explanation:
Hey, Ace here!
We have the equation [tex](6*10)^{-1} - (5*10)^{-3}[/tex]
Let's simplify by doing the parenthesis first:
[tex]60^{-1} - 50^{-3}[/tex]
According to our exponent rules, [tex]a^{-b}=\frac{1^{b}}{a^{b}}[/tex]
So let's simplify:
[tex]\frac{1^{1}}{60^{1}} - \frac{1^{3}}{50^{3}}[/tex]
Simplify further:
[tex]\frac{1}{60} - \frac{1}{125000}[/tex]
Find a common denominator (which, yes, is a pain):
[tex]\frac{1*6250}{60*6250} - \frac{1*3}{125000*3}[/tex]
Simplify:
[tex]\frac{6250}{375000}-\frac{3}{375000}[/tex]
Now perform the subtraction:
[tex]\frac{6247}{375000}[/tex]
That's your answer. Let me know if you have any questions.
