The 3 inside angles need to equal 180 degrees.

Angle K is given as 48 degrees.

Angle M would be 90 degrees.

Angle J = 180 - 90 - 48 = 42

Angle J = 42 degrees

Which exponential expression is equivalent to c?<br> Choose 1 answer

Pachacha [2.7K]

Answer:

As $\sqrt[5]{c}$ is the fifth root of c, therefore, $\sqrt[5]{c}$ can be written as: $\left(c\right)^{\frac{1}{5}}$

In other words,

$\:c^{\frac{1}{5}}=\sqrt[5]{c}$

Therefore, option C is correct.

Step-by-step explanation:

Given the expression

$\sqrt[5]{c}$

Here,

5 is the index

c is the radicand

As $\sqrt[5]{c}$ is the fifth root of c, therefore, $\sqrt[5]{c}$ can be written as: $\left(c\right)^{\frac{1}{5}}$

In other words,

$\:c^{\frac{1}{5}}=\sqrt[5]{c}$

Therefore, option C is correct.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.
