Write \(\frac{1}{x^{-1 / 2}}\) using a positive index.
Transpose $$L=\frac{\mu N^{2} A}{l}$$ for \(N\).
Make the specified variable the subject of the formula: (a) \(h=c+d+2 e\), for \(e\) (b) \(S=2 \pi r^{2}+2 \pi r h\), for \(h\) (c) \(Q=\sqrt{\frac{c+d}{c-d}}\), for \(c\) (d) \(\frac{x+y}{3}=\frac{x-y}{7}+2\), for \(x\)
If \(A+B+C=180\), find \(C\) when \(A=30\) and \(B=60\).
