Question

Tính giá trị biểu thức :

A = 426 + 2.(37 - 213) + 39 - 13

B = \(\left(\frac{1}{2}-\frac{3}{11}\right):\frac{1}{22}-10\)

 

Answer 1

\(A=426+2.\left(37-213\right)+39-13\)

\(A=426+2.\left(-176\right)+39-13\)

\(A=426+\left(-352\right)+39-13\)

\(A=74+39-13\)

\(A=113-13\)

\(A=100\)

Answer 2

\(B=\left(\frac{1}{2}-\frac{3}{11}\right):\frac{1}{22}-10\)

\(B=\frac{5}{22}:\frac{1}{22}-10\)

\(B=5-10\)

\(B=-5\)

Answer 3

A = 426 + 2 ( 37 - 213 ) + 39 - 13

   = 426 + 2.( - 176 ) + 39 - 13

   = 426 - 352 + 39 - 13

   = 74 + 39 - 13 

   = 113 - 13 

   = 100

Study well ! >_<

Answer 4

\(A=426+2.\left(37-213\right)+39-13\)

\(A=426-352+39-13\)

\(A=100\)

Answer 5

\(B=\left(\frac{1}{2}-\frac{3}{11}\right):\frac{1}{22}-10\)

\(B=\frac{5}{22}.22-10\)

\(B=5-10=-5\)

Answer 6

A=426+2(37-213)+39-13

=426+2(-176)+39-13

=426-352+39-13

=74+39-13=113-13=100

Answer 7

A = 426 + 2 . ( 37 - 213 ) + 39 - 13

A = 426 + 2 . ( - 176 ) + 39 - 13

A = 426 - 352 + 39 - 13

A = 74 + 39 - 13

A = 113 - 13

A = 100

Answer 8

\(B=\left(\frac{1}{2}-\frac{3}{11}\right):\frac{1}{22}-10\)

\(B=\frac{5}{22}:\frac{1}{22}-10\)

\(B=\frac{5}{22}.\frac{22}{1}-10\)

\(B=5-10\)

\(B=-5\)
