Question

Tính nhanh tính hợp lý(nếu có thể)
(-12)x54+54x(-88)
2x3 mũ 2+(-200):2 mũ 2-8x(-4)-2022 mũ 0

Answer 1

a: =54x(-100)=-5400

b: \(=18+\left(-200\right):4-8\cdot\left(-32\right)-1\)

=17-50+256

=-33+256

=223

Answer 2

a: =54x(-100)=-5400

b: \(=18+\left(-200\right):4-8\cdot\left(-32\right)-1\)

=17-50+256

=-33+256

=223

Answer 3

a, = 54 x \(\left[\left(-12\right)+\left(-88\right)\right]=54.\left(-100\right)=-5400\)

b, = \(2.3^2+\left(-200\right):2^2-8.\left(-4\right)-2022^0\)

\(=2.9+\left(-200\right):4+32-1\)

\(=18-50+32-1=-1\)
