Answer:

$6^{30}$

Step-by-step explanation:

Using the rules of exponents

$(a^m)^{n}$ ⇔ $a^{mn}$

$\frac{a^{m} }{a^{n} }$ ⇔ $a^{(m-n)}$

Given

$\frac{(6^-4)^{-9} }{6^6}$

= $\frac{6^{36} }{6^{6} }$

= $6^{(36-6)}$

= $6^{30}$

Answer:

42°

sin^-1(opposite/hypotenuse)=x

sin^-1(8/12)=x

Input into calculator

x=42°
