The inverse of matrix \(N = \begin{vmatrix} 2 & 3 \\ 1 & 4 \end{vmatrix}\) is
Answer Details
N = [2 3] N-1 = adjN|N| a d j N | N | adj N = ∣∣∣4−3−12∣∣∣ | 4 − 3 − 1 2 | |N| = (2 x4) - (1 x 3) = 8 - 3 =5 N-1 = 15 1 5 ∣∣∣4−3−12∣∣∣
Simplify \(\frac{3\frac{2}{3}\times\frac{5}{6}\times\frac{2}{3}}{\frac{11}{15}\times\frac{3}{4}\times\frac{2}{27}}\)
If 2q35 = 778, find q
If the numbers M, N, Q are in the ratio 5:4:3, find the value of \( \frac{2N-Q}{M} \)
Rationalize \( \frac{2-\sqrt{5}}{3-\sqrt{5}} \)
Simplify \( \left(\frac{16}{81}\right)^{\frac{1}{4}} \div \left(\frac{9}{16}\right)^{-\frac{1}{2}} \)
If log318 + log33 - log3x = 3, Find x.
Simplify \(\left(\sqrt{2}+\frac{1}{\sqrt{3}}\right)\left(\sqrt{2}-\frac{1}{\sqrt{3}}\right)\)
