Hello!</h2>
The answer is:
The correct option is:
C)
<h2>
Why?</h2>
To solve the problem, we need to remember the product of powers with the same base property, the property is defined by the following relation:
If we are multiplying two or more powers with the same base, we must keep the base and add/subtract the exponents.
So, we are given the expression:
We can see that both powers have the same base (4), so solving we have:
Hence, we have that the correct option is:
C)
Have a nice day!
The trigonometric expression sin 30° will be equal to cos 60°. Then the correct option is E.
<h3>How to convert the sine of an angle to some angle of cosine?</h3>
We can use the fact that:
sin(θ) = cos(90 - θ)
To convert the sine to cosine (but the angles won't stay the same unless it's 45 degrees).
The trigonometric expression sin 30° will be equal to
The sin 30° can be written as
sin 30° = cos(90° - 30)
sin 30° = cos 60°
Then the correct option is E.
