\(2^4\cdot5-\left[131-(13-4)^2\right]\)
\(=16\cdot5-\left[131-9^2\right]\)
\(=16\cdot5-\left[131-81\right]\)
\(=80-50=30\)
\(2^4.5-[131-(13-4)^2] \)
\(=16.5-[131-9^2]\)
\(=80-[131-81]\)
\(=80-50 \)
\(=30\)
24.5[131-(13-4)2 ]
=16.5-[131-92 ]
=80-[131-81]
=80-50
=30
24.5 - [ 131 - (13-4)2 ]
=16.5 - [ 131 - ( 9 )2 ]
=16.5- [ 131 - 81]
=80 - 50
=30
