Question

Mg giải gấp giúp mình ạ

Answer 1

2:

a: \(A=2^4\cdot5-\left[131-\left(13-4\right)^2\right]\)

\(=16\cdot5-\left[131-81\right]\)

=80-50

=30

b: \(B=2^3+3\cdot\left(\dfrac{1}{2}\right)^0-1+\left[\left(-2\right)^2:\dfrac{1}{2}\right]-8\)

\(=8+3-1+\left[4\cdot2\right]-8\)

=8+2

=10

Bài 1:

a: \(A=32,125-\left(6,325+12,125\right)-\left(37+13,675\right)\)

\(=32,125-12,125-6,325-13,675-37\)

=20-20-37

=-37

b: \(B=4,75+\left(-\dfrac{1}{2}\right)^3+0,5^2-3\cdot\dfrac{-3}{8}\)

\(=4,75-0,125+0,25+1,125\)

=5+1

=6
