Answer:
I = 20 amperes

Explanation:
The relation between current, voltage and resistance can be expressed using Ohm's law as follows:
V = I*R
where:
V is the volt = 100 volts
I is the current we want to calculate
R is the resistance = 5 Ohm

Substitute with the givens in the above relation to get the current as follows:
V = I*R
I = v/r
I = 100/5
I = 20 amperes

Hope this helps :)

I=20 amps.
By the way, did you know that this is Ohm's Law?

Answer:

$\frac{1}{4k^3}$

Step-by-step explanation:

It's already in a form that only ha positive exponents. Just to state it though you could rewrite it as $k*(4k^{4})^{-1}$ or $k*4^{-1}*k^{-4}$ The question asks for positive exponents though so yu don't need to do that.
