Please Help!!<br><br> Write in exponential form.

Karo-lina-s [1.5K]

ANSWER

$5{e}^{i \frac{5\pi}{3} }$

EXPLANATION

The exponential form of complex numbers is given by;

$z =r {e}^{i \theta}$

The given complex number in polar form is:

$5( \cos( \frac{5\pi}{3} + i \sin( \frac{5\pi}{3}) )$

We have r=5 from the question and

$\theta = \frac{5\pi}{3}$

We substitute these values to obtain the exponential form:

$z =5{e}^{i \frac{5\pi}{3} }$

The correct answer is C

First verify that y(x)y(x) satisfies the given differential equation. Then determine a value of the constant CC so that y(x)y(x)

zubka84 [21]

Answer:

at constant C = -56 satisfies the given condition of y(x)

Step-by-step explanation:

differentiate y(x) w.r.t.x

$y' (x ) = \frac{d}{dx} (\frac{1}{4} x^5 +Cx^{-3} )$

= $\frac{1}{4}\frac{d}{dx} (x^5) + C\frac{d}{dx} (x^{-3} )$

= $\frac{5}{4} x^4 - 3Cx^{-4}$

attached is the remaining part of the detailed solution and the sketch of the several typical solutions

Use the product property of roots to choose the expression equivalent to 3√5x*3√25x^2?

nignag [31]

Answer: $\sqrt[3]{125x^3}$ .

Step-by-step explanation: Given radical expression

$\sqrt[3]{5x} \times \sqrt[3]{25x^2}$ .

According to the product property of roots.

$\sqrt[n]{a} \times \sqrt[n]{b} = \sqrt[n]{a \times b}$

On applying above rule, we get

$\sqrt[3]{5x} \times \sqrt[3]{25x^2} = \sqrt[3]{5x \times 25x^2}$

5 × 25 = 125 and

$x \times x^2 = x^3$

Therefore,

$\sqrt[3]{5x \times 25x^2}= \sqrt[3]{125x^3}$

<h3>So, the correct option would be second option $\sqrt[3]{125x^3}$ .</h3>
