24x5-[131-(13-4)2]
=24x5-[131-92]
=24x5-[131-81]
=16x5-50
=80-50
=30
\(2^4.5-\left[131-\left(13-4\right)^2\right]\)
\(=16.5-\left[131-121\right]\)
\(=16.5-10\)\(=80-10=70\)
2⁴×5–[131–(13-4)²
=16×5–[131-(13-9²]
=80-[131-81]
=80-50=30 ai k mình mình k lại
Mk tính sai, làm lại :
\(2^4.5-\left[131-\left(13-4\right)^2\right]\)
\(=80-\left[131-91\right]\)\(=80-50=30\)
