Which property was used to rewrite log https://api.agilixbuzz.com/Resz/~Ey6YBAAAAAgLDBUexsJfHB.5rGOzcBm-rQDH5ZaE_3S2B/19809088,B84/Assets/assessmentimages/alg%202%20pt%202%20u4l4%2027.jpg power property power and quotient properties quotient property product and power properties

@Hero

hero (hero):

0. Translation of Instructions: Re-write the given expression in the expected form, then identify the properties you used to arrive at the correct result.

OpenStudy (18jonea):

I dont know how to do that @Hero

OpenStudy (18jonea):

6 not 5

hero (hero):

1. Rewrite the radical in fractional form.

OpenStudy (18jonea):

how would i do that?

hero (hero):

Apply the following rule, \(\sqrt[b]{x^a} = x^{a/b}\)

OpenStudy (18jonea):

8x^3/6

hero (hero):

If you're going to write horizontally, without LaTeX, you must use parentheses to clarify what in included in the exponent: 8x^(3/6)

hero (hero):

2. Simplify the fraction.

OpenStudy (18jonea):

what would i simplify

hero (hero):

What does 3/6 simplify to?

OpenStudy (18jonea):

1/2

hero (hero):

So what would be the resulting expression after simplification?

OpenStudy (18jonea):

8x/(3)

hero (hero):

I suppose you misunderstood what 8x^(3/6) means

hero (hero):

It means this: \(8x^{3/6}\) The 3/6 is an exponent by the way.

OpenStudy (18jonea):

ok

hero (hero):

One second, let me do this completely by hand first.

OpenStudy (18jonea):

ok

hero (hero):

Researching...

hero (hero):

Sorry for taking so long. I made a silly mistake while going over this.

hero (hero):

I'll just post the correct steps.

hero (hero):

\(\begin{align*}\sqrt[6]{8x^3} &= \sqrt[6]{2^3x^3}\\&=\sqrt[6]{(2x)^3}\\&=(2x)^{3/6}\\&={2x^{1/2}}\end{align*}\) Taking the log of that you get: \(\begin{align*}\log{\left(2x^{1/2}\right)} &= \dfrac{1}{2}\log{(2x)}\end{align*}\)

OpenStudy (18jonea):

so would this be the answer?

hero (hero):

Well, it says to point out which property or properties of logs were used to get that result.

hero (hero):

And there is only one property that was used. I guess that's your hint.

OpenStudy (18jonea):

power property

OpenStudy (18jonea):

is that right?

hero (hero):

It's correct.

OpenStudy (18jonea):

can you help me with 3-4 more?
