a, = 996 + 4 + 40 = 1000 + 40 = 1040
b, = 198 + 2 + 35 = 200 + 35 = 235
c, = ( 4 *25 )*(2 * 5)*55=100 * 10 * 55 = 55000
d, = 97*(36+64) = 97 * 100 = 9700
e, = (125+75)+(360+40)= 200 + 400 = 600
g, =10^2=100
a) \(996+44\)
\(=1040\)
b) \(37+198\)
\(=230\)
\(a,996+44=1040\)
\(d,97.36+64.97=97.\left(36+64\right)=97.100=9700\)
\(b,37+198=235\)
\(c,4.55.25.2.5=220.50.5=11000.5=55000\)
\(e,125+360+75+40=485+115=600\)
\(g,10^{12}:10^{10}=10^2=100\)
Tui nhầm câu b cho sửa lại kq = 235 nhé
Xin lỗi
