Đáp án : b = $100^{}$, c = $2002^{}$
Giải thích các bước giải:
b)
$2^{}$ x [($7^{}$- $3^{3}$ : $3^{2}$ ) : $2^{2}$ + $99^{}$] - $100^{}$
= $2^{}$ x [($7^{}$ - $3^{}$ ) : $2^{2}$ + $99^{}$] - $100^{}$
= $2^{}$ x [ $4^{}$ : $2^{2}$ + $99^{}$] - $100^{}$
= $2^{}$ x [$1^{}$ + $99^{}$] - $100^{}$
= $200^{}$ -$100^{}$ = $100^{}$
c)
$3^{2}$ x [($5^{2}$ - $3^{}$ ) : $11^{}$ ] - $2^{4}$ + $2^{}$ x $10^{3}$
= $9^{}$ x [$22^{}$ : $11^{}$] - $16^{}$ + $2^{}$ x $10^{3}$
= $9^{}$ x $2^{}$ - $16^{}$ + $2^{}$ x $1000^{}$
= $18^{}$ - $16^{}$+ $2000^{}$
= $2^{}$ + $2000^{}$
= $2002^{}$
