Question

tính bằng cách hợp lí nhất

Answer 1

g: \(\left(-3\right)^4\cdot10=81\cdot10=810\)

i: \(\left(-2\right)\cdot\left(-2\right)\cdot\left(-4\right)\cdot\left(-4\right)\cdot\left(-4\right)\)

\(=-2\cdot2\cdot4\cdot4\cdot4\)

\(=-2^2\cdot2^2\cdot2^2\cdot2^2=-2^8=-256\)

l: \(26\cdot\left(-125\right)-125\cdot\left(-36\right)\)

\(=125\cdot\left(-26\right)+125\cdot36\)

\(=125\left(-26+36\right)\)

\(=125\cdot10=1250\)

n: \(\left(-37\right)\cdot84+37\cdot\left(-16\right)\)

\(=37\cdot\left(-84\right)+37\cdot\left(-16\right)\)

\(=37\left(-84-16\right)=37\cdot\left(-100\right)=-3700\)
