A long-distance telephone company charges a rate of cents per minute or a -cent minimum charge per completed call, whichever

LiRa [457]

Answer: 50 cents

Step-by-step explanation:

Company charges 8 cents per call and the call in question is 3 minutes. Cost is;

= 3 * 8

= 24 cents

Company however stipulates that a call is 8 cents per minute or a 50-cent minimum charge per completed call, whichever is greater.

<em>50 cents is greater than the per minute total charge of 24 cents so the cost will be 50 cents.</em>

Which expression is equivalent to (x Superscript one-half Baseline y Superscript negative one-fourth Baseline z) Superscript neg

Darina [25.2K]

By using exponent properties, we will get the simplified expression:

$x^{-1}*y^{1/2}*z^2$

<h3>How to simplify the given expression?</h3>

Here we have the expression:

$(x^{1/2}*y^{-1/4}*z)^{-2}$

Remember the exponent properties:

$(a^n)^m = a^{n*m}$

And:

$(a*b)^n = (a^n)*(b^n)$

So using these two properties, we can rewrite:

$(x^{1/2})^{-2}*(y^{-1/4})^{-2}*(z)^{-2}\\\\(x^{-2*1/2})*(y^{-2*-1/4})*(z^{-2}})\\\\x^{-1}*y^{1/2}*z^2$

So we conclude that the completely simplified expression is:

$x^{-1}*y^{1/2}*z^2$
