Answer:

$\sin x = 0$ , $x = \pm \pi\cdot i$ , $\forall i \in \mathbb{N}_{O}$

Step-by-step explanation:

The following trigonometric equation is simplified by using identities:

$\sin x + \sin^{2}x + \cos^{2}x = 1$

$\sin x + 1 = 1$

$\sin x = 0$

Whose solutions are:

The answer is 100X because if you do 5x-4x first it will be 1x. Later on, if you do the exponent you have 1x times 1x. Then you do 1x+9x = 10x

Then you do 10x times 10x because of the exponent is telling you how times you do it and it equals to 100x.

Answer= 100x

I hope this helps YOU!
