<h3>Answer: Choice A</h3>

Reason:

Use the rule that $a^{b/c} = \sqrt[c]{a^b} = \left(\sqrt[c]{a}\right)^b$

This means, $(2a)^{6/5} = \sqrt[5]{(2a)^6} = \boldsymbol{\left(\sqrt[5]{2a} \ \right)^6}$

As another example, $m^{2/3} = \sqrt[3]{m^2} = \left(\sqrt[3]{m} \ \right)^2$

¿cuál de los siguientes valores de funciones es negativo? a. Sen 120° b. Sen 150° c. Cos 235° d. Cos 300°.

An X-axis and Y-axis rectangular coorganizing system splits the plane in to the four regions recognised as the quadrants. The cross point is indeed the source of the two axes and is made reference to as O. So, the calculation can be defined as follows:

Given:

$\bold{a)\ \sin 120^{\circ}}\\\\\bold{b)\ \sin 150^{\circ}}\\\\\bold{c)\ \cos 235^{\circ}}\\\\\bold{d)\ \cos 300^{\circ}}\\\\$

To find:

Find negative function values =?

Solution:

$\therefore \\\\\to \bold{\sin (180- \theta)= \sin \theta} \\\\\to \bold{\cos (180- \theta)= -\cos \theta} \\\\\to \bold{\cos (180+ \theta)= -\cos \theta} \\\\ \to \bold{\cos (360- \theta)= \cos \theta}$
