Can anyone answer this question for me and also if you’re able to give me the explanation on how to solve it also. PLEASE.

Answer:

 First option=$13950 is correct.

Why?

Total other cost =$15500

10% saving on other cost

=10% × $15500

=$1550

So total cost target on other cost for next month

=$15500-$1550

=$13950

Which expression is equivalent to 12 to the 10 over 12?

jonny [76]

<h3>Answer: Choice C</h3>

Work Shown:

$\frac{12^{10}}{12}\\\\\\\frac{12^{10}}{12^1}\\\\\\12^{10-1}\\\\\\12^{9}\\\\\\\frac{1}{12^{-9}}\\\\\\\left(\frac{1}{12}\right)^{-9}\\\\\\$

In the third step, I used the rule that $\frac{a^b}{a^c} = a^{b-c}$ . You subtract the exponents when dividing exponents of the same base.

After that, I used the rule $a^{-b} = \frac{1}{a^b}$ which is the same as saying $a^{b} = \frac{1}{a^{-b}}$ to end up with choice C as the answer.
