Question

If A to the power of negative 1 end exponent equals fraction numerator 1 over denominator 3 end fraction blank open square brackets table row 1 4 cell negative 2 end cell row cell negative 2 end cell cell negative 5 end cell 4 row 1 cell negative 2 end cell 1 end table close square brackets blankand open vertical bar A close vertical bar equals 3 blankthen Adj A=

  1. 3 open square brackets table row 1 4 cell negative 2 end cell row cell negative 2 end cell cell negative 5 end cell 4 row 1 cell negative 2 end cell 1 end table close square brackets    
  2. fraction numerator 1 over denominator 3 end fraction open square brackets table row cell negative 1 end cell cell negative 4 end cell 2 row 2 5 cell negative 4 end cell row cell negative 1 end cell 2 cell negative 1 end cell end table close square brackets    
  3. open square brackets table row 1 4 cell negative 2 end cell row cell negative 2 end cell cell negative 5 end cell 4 row 1 cell negative 2 end cell 1 end table close square brackets    
  4. 1    

The correct answer is: open square brackets table row 1 4 cell negative 2 end cell row cell negative 2 end cell cell negative 5 end cell 4 row 1 cell negative 2 end cell 1 end table close square brackets
