Answer:

13. $\frac{\sqrt[5]{x^4} }{x}$ .

14. $v = \pm3\sqrt{5}$

15. 2.

Step-by-step explanation:

13. $x^{1/5} * x^{-2/5}$

= $x^{1/5 + (-2/5)}$

= $x^{1/5 - 2/5}$

= $x^{-1/5}$

= $\frac{1}{x^{1/5}}$

= $\frac{x^{4/5}}{x^{1/5 + 4/5}}$

= $\frac{x^{4/5}}{x}$

= $\frac{\sqrt[5]{x^4} }{x}$ .

14. $v^2 - 45 = 0$

$v^2 = 45$

$\sqrt{v^2} = \pm\sqrt{45}$

$\sqrt{v^2} = \pm\sqrt{3^2 * 5}$

$v = \pm3\sqrt{5}$ .

15. $\sqrt[3]{2} * \sqrt[3]{4}$

= $\sqrt[3]{2 * 4}$

= $\sqrt[3]{2 * 2 * 2}$

= $\sqrt[3]{2 ^3}$

= 2.

Hope this helps!

Determine if the sequence is arithmetic. If it is, find the term named in the problem.

Brums [2.3K]

Answer:

$a_{39}$ <em>= 279</em>

Step-by-step explanation:

$a_{n}$ = $a_{1}$ + (n - 1)d

d = $a_{2}$ - $a_{1}$

~~~~~~~~~

d = - 17 + 25 = - 9 + 17 = - 1 + 9 = 8

$a_{39}$ = - 25 + 8(39 - 1) = 279

$a_{39}$ <em>= 279</em><em> </em>
