Answer:
1/2
Step-by-step explanation:
16^-1/4
We know that a^ -b = 1/a^b
1/( 16^1/4)
Rewriting 16 as 2^4
1/( 2^4^1/4)
We know that a^b^c = a^ (b*c)
1/( 2^(4*4))
1/2^1
1/2

Let's go manual for now.
Let's covert pi/4 to angle
1⁰ =π/180
1 radian =180/π
Therefore π/4 × 180/π
∅ =45⁰
Sin-¹(tan 45⁰)
Tan 45⁰= 1
Sin-¹ (1) = 90⁰. Press { sin,-¹ (1) } on your calculator
Sin-¹ (tan pi/4) = 90⁰
