A.996+44

B.37+198

C.4×55×25×2×5

D.97×36+64×97

E.125+360+75+40

G.10^12÷10^10

 

Answer 1

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

Answer 2

a) \(996+44\)

    \(=1040\)

b) \(37+198\)

     \(=230\)

Answer 3

\(a,996+44=1040\)                                                                 

\(d,97.36+64.97=97.\left(36+64\right)=97.100=9700\)

\(b,37+198=235\)

\(c,4.55.25.2.5=220.50.5=11000.5=55000\)

\(e,125+360+75+40=485+115=600\)

\(g,10^{12}:10^{10}=10^2=100\)

Answer 4

Tui nhầm câu b cho sửa lại kq = 235 nhé

Xin lỗi

Chúc bạn học tốt~~

Answer 5

A.996+44=996+4+40=1000+40=1040

B.37+198=35+2+198=35+200=235

C.4.55.25.2.5=(4.25).(2.5).55=100.10.55=1000.55=55000

D.97.36+64.97=97(64+36)=97.100=9700

E.125+360+75+40=(125+75)+(360+40)=200+400=600

G.10^12:10^10=10^2.10^10:10^10=10^2.1=100

Answer 6

a) =1000-4+44

=( 1000+44) -4= 1044 - 4 = 1040

b)= 37+200-2 = (37+200) - 2 =235

c) = (4.25) .  (2.5) . 55= 100 . 10 . 55 = 1000.25 = 25000

d) =97.(36+64)=97.100=9700

e) = ( 125 + 75) + ( 360 + 40) = 200 +400=600

g) 10¹² : 10¹⁰ = 10² = 100
