Question

The value of open vertical bar table row cell 1 to the power of 2 end exponent end cell cell 2 to the power of 2 end exponent end cell cell 3 to the power of 2 end exponent end cell row cell 2 to the power of 2 end exponent end cell cell 3 to the power of 2 end exponent end cell cell 4 to the power of 2 end exponent end cell row cell 3 to the power of 2 end exponent end cell cell 4 to the power of 2 end exponent end cell cell 5 to the power of 2 end exponent end cell end table close vertical bar is

  1. 8    
  2. – 8    
  3. 400    
  4. 1    

The correct answer is: – 8


    open vertical bar table row cell 1 to the power of 2 end exponent end cell cell 2 to the power of 2 end exponent end cell cell 3 to the power of 2 end exponent end cell row cell 2 to the power of 2 end exponent end cell cell 3 to the power of 2 end exponent end cell cell 4 to the power of 2 end exponent end cell row cell 3 to the power of 2 end exponent end cell cell 4 to the power of 2 end exponent end cell cell 5 to the power of 2 end exponent end cell end table close vertical bar{Operate R subscript 3 end subscript rightwards arrow R subscript 3 end subscript minus R subscript 2 end subscript,R subscript 2 end subscript rightwards arrow R subscript 2 end subscript minus R subscript 1 end subscript}
    = open vertical bar table row 1 4 9 row 3 5 7 row 5 7 9 end table close vertical bar equals 1 left parenthesis 45 minus 49 right parenthesis minus 4 left parenthesis 27 minus 35 right parenthesis plus 9 left parenthesis 21 minus 25 right parenthesis
    = negative 4 plus 32 minus 36 equals negative 8.
