(a) Express \(\frac{1}{u}+\frac{1}{v}\) as a single fraction. (b) Hence find the reciprocal of \(\frac{1}{u}+\frac{1}{v}\).
Evaluate \(V=r_{1}^{2}+r_{2}^{2}\) when \(r_{1}=0.1\) and \(r_{2}=0.05\)
Transpose $$L=\frac{\mu N^{2} A}{l}$$ for \(N\).
Factorise (a) \(2 x^{2}-11 x+5\) (b) \(2 x^{2}+13 x+15\)
Remove the brackets from \(\left(7 x^{2}\right)^{-3} .\)
