PLEASE HELP ME OUT!!
Zielflug [23.3K]

Answer:

  (d)  1/√(s³)

Step-by-step explanation:

The expression can be simplified by making use of the rules of exponents.

<h3>Rules of exponents</h3>

The relevant rules are ...

  a^b\cdot a^c=a^{b+c}\\\\(a^b)^c=a^{bc}\\\\\left(\dfrac{a}{b}\right)^c=\dfrac{a^c}{b^c}\\\\a^{b/c}=\sqrt[c]{a^b}

<h3>Application</h3>

The given expression can be simplified by applying these rules.

  \left(\dfrac{1}{s^{-1}\cdot s^8}\right)^{3/14}=\dfrac{1}{(s^{-1+8})^{3/14}}=\dfrac{1}{s^{7\cdot3/14}}=\dfrac{1}{s^{3/2}}=\boxed{\dfrac{1}{\sqrt{s^3}}}

What is another expression for...<br> 20% - $117.76 = $16.62<br> and how dose it work?
vladimir2022 [97]

Answer:

0.20 - $117.76= $16.62

Step-by-step explanation:

if you  have a percentage you can always turn it into a decimal just put the number behind the period: 70% = .70, 49% = .49%       ....

then you do the rest of the equation and BOOM!

20% - $117.76 = $16.62 = 0.20 - $117.76= $16.62.
