Question

A= -5^22{-222[-122-(100-5^22)+2022]}

HT.Phong (9A5) · Accepted Answer

$A=-5^{22}\left\{-222\left[-122-\left(100-5^{22}\right)+2022\right]\right\}$

$A=-5^{22}\left\{-222\left[1900-\left(100-5^{22}\right)\right]\right\}$

$A=-5^{22}\left[-222\left(1900-100+5^{22}\right)\right]$

$A=-5^{22}\left[-222\left(1800+5^{22}\right)\right]$

$A=-5^{22}\left(-399600-222\cdot5^{22}\right)$

$A=399600\cdot5^{22}+222\cdot5^{44}$Câu trả lời: $A=-5^{22}\left\{-222\left[-122-\left(100-5^{22}\right)+2022\right]\right\}$

$A=-5^{22}\left\{-222\left[1900-\left(100-5^{22}\right)\right]\right\}$

$A=-5^{22}\left[-222\left(1900-100+5^{22}\right)\right]$

$A=-5^{22}\left[-222\left(1800+5^{22}\right)\right]$

$A=-5^{22}\left(-399600-222\cdot5^{22}\right)$

$A=399600\cdot5^{22}+222\cdot5^{44}$
