C. $\huge\frac{1}{3x {y}^{2} {z}^{4}}$

Step-by-step explanation:

$(9 {x}^{2} {y}^{4} {z}^{8} )^{ - \frac{1}{2} } \\ \\ = ( {3}^{2} {x}^{2} {y}^{4} {z}^{8} )^{ - \frac{1}{2} } \\ \\ = \frac{1}{( {3}^{2} {x}^{2} {y}^{4} {z}^{8} )^{ \frac{1}{2} }} \\ \\ = \frac{1}{(3x {y}^{2} {z}^{4})^{2 \times \frac{1}{2} } } \\ \\ = \frac{1}{3x {y}^{2} {z}^{4}} \\ \\ \red{ \bold{ \therefore \: (9 {x}^{2} {y}^{4} {z}^{8} )^{ - \frac{1}{2} } = \frac{1}{3x {y}^{2} {z}^{4}} }}\\$

A water cooler can hold 50 pt of water.

Nookie1986 [14]

Water cooler holds = 50 pt of water

1 L≈1.06 qt (which is the value of US liquid quart)

1.06 qt = 2.12 pt (which is the value of US liquid pint)

So when we are calculating how many liters of water cooler holds, divide the 50pt with 2.12pt

50pt/2.12pt = 23.6 Liters

<span>So 23.6 is the correct answer.</span>

Identify the terms and like terms in the expression 14 – 8x– 6 - 10x.

grin007 [14]

Answer:

Like terms are similar and terms are different.

Like terms :-

-10
14
-6

They are similar.

Terms :-

-8x²
-10x

One has an exponent and other does not which means they are not like terms and are only terms.

Hope this helps, thank you :) !!
