Question

bài 1: tính

a, 3860 - 86 x ( 370 - 183 x 2 )

Answer 1

\(3860-86.\left(370-183.2\right)\)

\(=3860-86.\left(370-366\right)\)

\(=3860-86.4\)

\(=3860-344\)

\(=3516\)

Vậy : \(3860-86.\left(370-183.2\right)=3516\)

Answer 2

\(3860-86\left(370-183\times2\right)\)

= \(3860-86\times\left(370-366\right)\)

= \(380-86\times4\)

= \(380-344\)

= \(36\)

Answer 3

a)3860-86.(370-183.2)

=3860-86.(370-366)

=3860-86.4

=3860-344

=3516

Answer 4

=3860−86.(370−366)

=3860−86.4

=3860−344

=3516

Answer 5

3860-86x(370-183x2)

=3860-86x(370-366)

=3860-86x4

=3860-344

=3516

Answer 6

\(a.\)\(3860-86.\left(370-183.2\right)\)

\(=3860-86.\left(370-366\right)\)

\(=3860-86.4\)

\(=3860-344\)

\(=3516\)
