Answer:

${( \sqrt{ {x}^{ - 3} }) }^{5} = ({( {x}^{ - 3}) }^{ \frac{1}{2} } ) ^{5} \\ \\ = {x}^{ - 3 \times \frac{1}{2} \times 5} = {x}^{ - \frac{15}{2} } = \frac{1}{ {x}^{ \frac{15}{2} } }$

Or ;

${( \sqrt{ {x}^{ - 3} } )}^{5} = {( \sqrt{ \frac{1}{ {x}^{3} }} })^{5} = ( { \frac{ \sqrt{1} }{ \sqrt{ {x}^{3} } } })^{5} \\ \\ = ( { \frac{1}{ \sqrt{x} \sqrt{ {x}^{2} } } })^{5} = ({ \frac{1}{ x\sqrt{x} }})^{5} \\ \\ = ( \frac{ {(1)}^{5} }{ {x}^{5} ( \sqrt{x} )^{5} } ) = \frac{1}{ {x}^{5} \times {x}^{ \frac{1}{2} \times 5 } } \\ \\ = \frac{1}{ {x}^{5} \times {x}^{ \frac{5}{2} } } = \frac{1}{ {x}^{5} \sqrt{ {x}^{5} } } \\ \\ = \frac{1}{ {x}^{5} \sqrt{ {x}^{4} {x}^{1} } } = \frac{1}{ {x}^{5} \sqrt{x} \sqrt{( { {x}^{2} })^{2} } } \\ \\ = \frac{1}{ {x}^{5} {x}^{2} \sqrt{x} } = \frac{1}{ {x}^{7} \sqrt{x} } = \frac{ \sqrt{x} }{ {x}^{8} }$

Which expressions are equivalent to 2(4f+2g)

Tresset [83]

Hello!

Answer:

↓↓↓↓↓↓↓↓

$=8f+4g$

Step-by-step explanation:

1. Apply the distributive law.

$a=2, b=4f, c=2g$

$=2*4f+2*2g$

2. Simplify.

$2*4f+2*g: 8f+4g$

$2*4f+2*2g$

3. Multiply the numbers.

$2*4=8$

$=8f+2*2g$

$2*2=4$

$=8f+4g$

Answer⇒ $8f+4g$

Hope this helps!

denpristay [2]

Answer:

One is a question and the other is a prediction.

Step-by-step explanation:

A quantitative research is based on numbers and data.

A research hypothesis is a prediction or an explanation that will be proven right or wrong given the results found in the research. And the quantitative research question is a question that will define the porpuse and will guide what we want to get out of the investigation.

Thus, the characteristic that distinguishes them is:

One is a question and the other is a prediction.

Where the question is the quantitative research question and the prediction is the research hypothesis.
