We can form this algebraic equation to work the equation out:

16 + 2x = -24
2x = -40
x - 20

Hope I helped.

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:

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

xenn [34]

Answer:

a8=10935

Step-by-step explanation:

A geometric sequece is a sequence of the form

$a_n=a\cdit r^{n-1}$

in our case we know that $a=a_1=5$ and $r=3$ , hence

$a_8=5 \cdot 3^7=10935$
