What is the difference between a straightedge and a ruler?

Choice C)

A straightedge can create a straight line, but can't measure. A ruler can create straight lines and measure distance.

Explanation:

A straight edge is anything straight you use to help draw straight lines. An example would be a piece of unmarked paper, or you can use a card perhaps. There are no markings on a straight edge to help measure distance. All you can do draw straight lines. A ruler is effectively a straightedge but with markings on it to help measure distance.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
