ghi dấu lại cho mk hiểu vs bạn k/quả là bao nhiu

\(a,3^3+3^2-\left(2^7:2^5+7^8:7^7\right)=27+9-\left(2^2+7\right)=36-11=25\)

\(b,27.77+27.27-27=27\left(77+27-1\right)=27.103=2781\)

\(c,52:\left(43-30\right)+144-16=52:13+128=4+128=132\)

\(f,3^2.101-3^2.101^0=3^2\left(101-101^0\right)=9\left(101-1\right)=9.100=900\)
