\(B=136.25+75.136-6^2.10^2\)
\(=136.\left(75+25\right)-36.100\)
\(=136.100-36.100\)
\(=\left(136-36\right).100\)
\(=100.100=10000\)
\(C=2^3.5^3-\left\{7^2.2^3.5^2.\left[4^3:8+11^2:121-2\left(37-5.7\right)\right]\right\}\)
\(=10^3-\left\{49.8.25.\left[8+1+2.2\right]\right\}\)
\(=1000-\left(49.200.13\right)\)
\(=1000-127400\)
\(=-126400\)
Bài này đơn giản thôi bạn
B= 136.(25+75)-36.100
B= 136. 100-36.100
B= 100.(136-36)
B= 100.100
B= 10000
