Question

(2x)^-1 how do u put this into a positive exponent and a fraction? 20 points

Answer 1

For this case we have that by definition of power properties it is fulfilled that:

$a ^ {-1} = \frac {1} {a ^ 1} = \frac {1} {a}$

Then, if we have the following expression:

$(2x)^{ -1}$

Applying the property, we can rewrite the expression as:

$\frac {1} {(2x) ^ 1} = \frac {1} {2x}$

Answer:

$\frac {1} {2x}$
