Choose the correct simplification of the expression (7ab3)2.

Brums [2.3K]

You can use this equation to help you: (ab)^2 = a^2 b^2. And also (a^m)^n = a^m*n

So, here it is:

(7ab^3)^2 = 7^2 a^2 b^3*2 = 49a^2b^6

The correct answer is the third one - 49 a^2 b^6.

Answer:

$1 + { \sin} \theta$

Step-by-step explanation:

$\frac{ { \cos}^{2} \theta}{1 - \sin \theta} \\ \\ = \frac{ { \cos}^{2} \theta}{(1 - \sin \theta)} \times \frac{(1 + \sin \theta)}{(1 + \sin \theta)} \\ \\ = \frac{{ \cos}^{2} \theta(1 + { \sin} \theta)}{(1 - { \sin}^{2} \theta)} \\ \\ = \frac{{ \cancel{ \cos}^{2} \theta}(1 + { \sin} \theta)}{ \cancel{{ \cos}^{2} \theta}} \\ \\ = 1 + { \sin} \theta$
