Answer: Choice D $c^{5/7}$

Explanation:

The rule we use is

$\left(\sqrt[n]{x}\right)^m = x^{m/n}$

The denominator n is the index of the root

With that rule in mind, we can say

$\left(\sqrt[7]{c}\right)^5 = c^{5/7}$

Two consecutive even numbers are such that five times the smaller number , subtracted from eight times the bigger gives 58. Find

olga55 [171]

Answer:

$14\text{ and }16$

Step-by-step explanation:

Let the smaller number be $x$ . Since they are consecutive even numbers, the larger number can be represented by $x+2$ .

Therefore, we have the following equation:

$8(x+2)-5x=58,\\8x+16-5x=58,\\3x=42,\\x=\boxed{14}$

Thus, the larger number is $x+2=\boxed{16}$

Show that the function f(x)= integral from x to 3x 1/t ft is constant on the interval (0, positive infinity)

jarptica [38.1K]

$\int\limits^{3x}_x { \frac{1}{t} } \, dt$
integrate to get
$[ln|t|]^{3x}_x=ln|3x|-ln|x|=ln| \frac{3x}{x}| =ln |3|=ln(3)$
this only is true when x>0
when x turns negative, we get -ln(3) because of math
