Let f(x) = cx^k be a power function such that f(13) is four times the size of f(1). What is the power k?
Ivenika [448]

Answer:

0.540

Step-by-step explanation:

Hi there,

To get started in order to solve this, please recall the property of logarithms.

This question is a bit tricky, but doable. Best way to solve this is first compare the two functions:

f(x) = cx^{k} \\ f(13)=4f(1)  

Now, let's see what the function gives at 13 and 1:

f(13)=c13^{k}\\f(1)=c1^{k}

Something to recognize is that 1 to the power of <em>anything</em> is just 1, so f(1) is reduced to:

f(1)=c  We are making progress!

Next, we can set both f(13) forms equivalent to each other, watch this:

f(13)=f(13) = 4f(1) but we know what f(1) is equal to, and let's substitute our knowns:

c13^{k}=4c1^{k} = 4c the c constant on both left and right side cancel out:

13^{k}=4 Now, take the logarithm form of both side of the equation. I used natural log, but you can also use common logs:

ln(13^{k})=ln(4)  ⇒ k*ln(13)=ln(4) this was performed using <em>the power  log rule. </em>

Isolate k:

k=\frac{ln(4)}{ln(13)} =0.540 using a calculator.

Plz write this on paper help me and send it❤️

Answer:

1. 27^{\frac{2}{3} } =9

2. \sqrt{36^{3} } =216

3. (-243)^{\frac{3}{5} } =-27

4. 40^{\frac{2}{3}}=4\sqrt[3]{25} =4325

5. Step 4: (\frac{343}{27}) ^{-1} =\frac{27}{343}

6. D. -72cd^{7}

Step-by-step explanation:

Use the following properties:

a^{\frac{x}{y} } =\sqrt[x]{a^{y} }

\sqrt[n]{ab} =\sqrt[n]{a} \sqrt[n]{b}

a^{-n} =\frac{1}{a^{n} }

(xy)^{z} =x^{z} y^{z} \\\\

(x^{y}) ^{z} =x^{yz}

x^{y} x^{z} =x^{y+z}

So:

1. 27^{\frac{2}{3} } =\sqrt[3]{27^{2}} =\sqrt[3]{729} }=9

2. \sqrt{36^{3} } =\sqrt{36*36*36} =\sqrt{36} \sqrt{36}  \sqrt{36} =6*6*6=216

3. (-243)^{\frac{3}{5} } =\sqrt[5]{-243^{3} } =\sqrt[5]{-14348907} =-27

4. 40^{\frac{2}{3}}=\sqrt[3]{40^{2} } =\sqrt[3]{2^{6} 5^{2} } =\sqrt[3]{2^{6} } \sqrt[3]{5^{2} } =2^{\frac{6}{3} } 5^{\frac{2}{3} } =4 *5^{\frac{2}{3} } =4\sqrt[3]{5^{2} } =4\sqrt[3]{25}=4325

5. (\frac{343}{27}) ^{-1} =\frac{1}{\frac{343}{27} } =\frac{27}{343}

6.

(-8c^{9} d^{-3} )^{\frac{1}{3} } *(6c^{-1}d^{4})^{2} =\sqrt[3]{-8} c^{3} d^{-1} 36c^{-2} d^{8} \\\\-2c^{3} d^{-1} 36c^{-2} d^{8}=-72cd^{7}
