Pachacha [2.7K]

Answer: -2 $x^{8}y^{12}$

Explanation:

We have given that,

∛-8 $x^{24}$ $y^{36}$

Now we will using the formula,

i.e. (√ab=√a×√b)

=∛-8×∛ $x^{24}$ ×∛ $y^{36}$

Here, we use the formula i.e.

$(a^{m})^{1/_n}$ = $a^{m/_n}$

∴ -2× $x^{{24}/_3}$ × $y^{36/3}$

= -2 $x^{8}$ $y^{12}$

Write each polynomial in standard form. 6y5 – 4y8 – 2 + 4y3

Fed [463]

Answer:

The standard form is :

$- 4 {y}^{8} + 6 {y}^{5} + 4 {y}^{3} - 2$

Step-by-step explanation:

A polynomial in standard form will be in decreasing powers of the variable.

The given polynomial is

$6 {y}^{5} - 4 {y}^{8} - 2 + 4 {y}^{3}$

We rearrange the terms in descending powers of y.

We start with the term with the highest degree and end with the term with the least degree.

$- 4 {y}^{8} + 6 {y}^{5} + 4 {y}^{3} - 2$

lions [1.4K]

Suppose $y_p=a_0+a_1t$ is a solution to the ODE. Then ${y_p}'=a_1$ and ${y_p}''=0$ , and substituting these into the ODE gives

$a_1-4(a_0+a_1t)=7t+5\implies\begin{cases}-4a_1=7\\-4a_0+a_1=5\end{cases}\implies a_0=-\dfrac{27}{16},a_1=-\dfrac74$

Then the particular solution to the ODE is

$y_p=-\dfrac{27}{16}-\dfrac74t$

PLEASE HELP!!!! see attachment below… I bet you cant solve this:

d1i1m1o1n [39]

Answer:

0

Step-by-step explanation:

<u>For each odd i the term is:</u>

(-1) $^{i}$ (5!*5/4!) $^{1/2}$ = - $\sqrt{25}$

<u>For each even i the term is:</u>

(-1) $^{i}$ (5!*5/4!) $^{1/2}$ = $\sqrt{25}$

So the sum of the first 100 terms is zero
