${[\begin{array}{c} 1 & 0.042 & 0.042 & 0.042 \\ 0.0351 & 1 & 0.0351 & 0.0351 \\ 0.033 & 0.033 & 1 & 0.033 \\ 0.0233 & 0.0233 & 0.0233 & 1 \end{array}]}^{- 1} [\begin{array}{c} 79400 \\ 67800 \\ 63600 \\ 46400 \end{array}]$

Step 1

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{1}{[\begin{array}{c} 1 & 0.042 & 0.042 & 0.042 \\ 0.0351 & 1 & 0.0351 & 0.0351 \\ 0.033 & 0.033 & 1 & 0.033 \\ 0.0233 & 0.0233 & 0.0233 & 1 \end{array}]} [\begin{array}{c} 79400 \\ 67800 \\ 63600 \\ 46400 \end{array}]$
