Option d:
is the correct answer.
Explanation:
The expression is 
We need to simplify the expression, using the product of powers.
The product of powers states that "when multiplying two powers with the same base the exponent values can be added up".
Thus, grouping the same base and adding the exponent values from the expression
, we have,

Adding the exponent, we get,

Thus, the simplified expression is 
Hence, Option d is the correct answer.
Answer:
Therefore,
The value of arcsin(0) is 0° or 180° or 360° or 540° or n×180° so on.
Step-by-step explanation:
To Find:
arcsin(0) in degrees =?
Solution:
' arcsin ' a mathematical function that is the inverse of the sine function.
Therefore, arcsin (x) is called the inverse sine function.
It is the angle whose sine is the number x.
So here we require angle in degree for which the Sine is '0'.
It is also written as

We Know that

Therefore,

Also integer multiples of 180° will have

Where n = integer
Therefore for '0' we can have 2×180° , 3×180° , 4×180°....and so on i.e 360° , 540° and so on
Therefore,
The value of arcsin(0) is 0° or 180° or 360° or 540° or n×180° so on.
