Question

$open vertical bar table row cell b to the power of 2 end exponent plus c to the power of 2 end exponent end cell cell a to the power of 2 end exponent end cell cell a to the power of 2 end exponent end cell row cell b to the power of 2 end exponent end cell cell c to the power of 2 end exponent plus a to the power of 2 end exponent end cell cell b to the power of 2 end exponent end cell row cell c to the power of 2 end exponent end cell cell c to the power of 2 end exponent end cell cell a to the power of 2 end exponent plus b to the power of 2 end exponent end cell end table close vertical bar equals$

$a b c$
$4 a b c$
$4 a^{2} b^{2} c^{2}$
$a^{2} b^{2} c^{2}$

The correct answer is: $4 a to the power of 2 end exponent b to the power of 2 end exponent c to the power of 2 end exponent$

$capital delta equals open vertical bar table row cell b to the power of 2 end exponent plus c to the power of 2 end exponent end cell cell a to the power of 2 end exponent end cell cell a to the power of 2 end exponent end cell row cell b to the power of 2 end exponent end cell cell c to the power of 2 end exponent plus a to the power of 2 end exponent end cell cell b to the power of 2 end exponent end cell row cell c to the power of 2 end exponent end cell cell c to the power of 2 end exponent end cell cell a to the power of 2 end exponent plus b to the power of 2 end exponent end cell end table close vertical bar$
= $negative 2 open vertical bar table row 0 cell c to the power of 2 end exponent end cell cell b to the power of 2 end exponent end cell row cell b to the power of 2 end exponent end cell cell c to the power of 2 end exponent plus a to the power of 2 end exponent end cell cell b to the power of 2 end exponent end cell row cell c to the power of 2 end exponent end cell cell c to the power of 2 end exponent end cell cell a to the power of 2 end exponent plus b to the power of 2 end exponent end cell end table close vertical bar$ ,by $R subscript 1 end subscript rightwards arrow R subscript 1 end subscript minus left parenthesis R subscript 2 end subscript plus R subscript 3 end subscript right parenthesis$
= $negative 2 open vertical bar table row 0 cell c to the power of 2 end exponent end cell cell b to the power of 2 end exponent end cell row cell b to the power of 2 end exponent end cell cell a to the power of 2 end exponent end cell 0 row cell c to the power of 2 end exponent end cell 0 cell a to the power of 2 end exponent end cell end table close vertical bar$ , by $R subscript 2 end subscript rightwards arrow R subscript 2 end subscript minus R subscript 1 end subscript R subscript 3 end subscript rightwards arrow R subscript 3 end subscript minus R subscript 1 end subscript$
= $negative 2 left curly bracket negative c to the power of 2 end exponent left parenthesis b to the power of 2 end exponent a to the power of 2 end exponent right parenthesis plus b to the power of 2 end exponent left parenthesis negative c to the power of 2 end exponent a to the power of 2 end exponent right parenthesis right curly bracket equals 4 a to the power of 2 end exponent b to the power of 2 end exponent c to the power of 2 end exponent$ .
Trick: Put $alpha$ so that the option give different values

In the expansion of $fraction numerator 1 plus x over denominator 1 factorial end fraction plus fraction numerator left parenthesis 1 plus x right parenthesis to the power of 2 end exponent over denominator 2 factorial end fraction plus fraction numerator left parenthesis 1 plus x right parenthesis to the power of 3 end exponent over denominator 3 factorial end fraction plus..... comma$ the coefficient of $x to the power of n end exponent$ will be

Round the number 5432 to the nearest hundred.

For rounding off to the nearest hundred, we can also look at the number formed by the tens place digit and one place digit. If the number formed is less than 50,we round down and if the number is 50 or more we round up.

Round the number 5432 to the nearest hundred.
