a) 125 × 6 = 6 × 125    

b) (12 – 5) × 8 = 8 × 7

=>6000x=12000

hay x=2

125.(-6).x.(-8)=12000

125.[(-6).(-8)].x=12000

145.48.x=12000

6000.x=12000

x=12000:6000

x=2

\(=\sqrt{125:5}+\sqrt{8.50}+6\)

\(=\sqrt{25}+\sqrt{400}+6=5+20+6=31\)

\(\sqrt{125}:\sqrt{5}+\sqrt{8}.\sqrt{50}+6\)

\(\sqrt{\dfrac{125}{5}}+\sqrt{400}+6\)

\(5+20+6=31\)

(-4).(+125).(-25).(-6).(-8)

`(6^10:6^8):{780:[87.5-(125+5.7^2)+13.5]}`

12 x 125 x 24 x 50

= (12 x 50) x (125 x 24)

(Tíck cho mình với nhé!)

12x125x24x50

\(\text{12 x 125 x 24 x 50}=1800000\)

(-4).125.(-25).(-6).(-8)

= 600000

kb vs tớ nha các bạn

thanks

(-4).125.(-25).(-6).(-8)

= [ 125. (-8)].[(-25).(-4)].(-6)

\(=6.10^{2+3}=6.10^5\)

\(=600000\)
