a) \(x.125=32250\)

\(x=32250:125\)

\(x=258\)

b) \(39975:x=123\)

\(x=39975:123\)

\(x=325\)

\(x\times125=32250\)

\(\Rightarrow x=258\)

_____

\(39975:x=123\)

\(\Rightarrow x=325\)

a)Xx125=32250

⇒ X=32250:125

⇒ X=258

b) 39975:X=123

⇒ X=39975:123

1200000

Bằng 1200000 nhé!

75x8x16x125=1200000

Ủng hộ nha

\(25\times20\times125\times8-8\times30\times5\times125\\ =125\times500\times8-8\times150\times125\\ =125\times4000-1200\times125\\ =125\times\left(4000-1200\right)\\ =125\times2800\\ =350000\)

(-64)x125=x³

     -8000=x³

vì -8000=-20³=>x=-20

vậy -5x₀=-5.(-20)1=100

Bang 100 

NHỚ  CHO MK NHA !!!!!!!!!!!!!!!!

Tich mình mình đi các bạn ơi

\(\frac{120\times999+120}{2\times4\times0,8\times5\times2,5\times125}\)

\(=\frac{120\times1000}{\left(125\times0,8\right)\left(4\times2,5\right)\left(2\times5\right)}\)

\(=\frac{120000}{100\times10\times10}\)

\(=\frac{120000}{10000}\)

\(=\frac{12}{1}=12\)

(-64) . 125 = x³

=> \(\left(-4\right)^3.5^3=x^3\)

=> \(\left(-4.5\right)^3=x^3\)

=> \(\left(-20\right)^3=x^3\)

=> x = -20

=> -5x₀ = \(-5.\left(-20\right)=100\)

tao ghét olm

(-64) . 125 = x³

=> $\left(-4\right)^3.5^3=x^3$(−4)3.53=x3

=> $\left(-4.5\right)^3=x^3$(−4.5)3=x3

=> $\left(-20\right)^3=x^3$(−20)3=x3

=> x = -20

=> -5x₀ = $-5.\left(-20\right)=100$

x3=(-64).125

x3=-8000

=>x=-20

=>(-5).x=(-5).(-20)=100

tk nha bạn

thank you bạn

(^_^)

= (5 x 2) x (125 x 8) x (25 x 4)
= 10 x (125 x 8) x (25 x 4)
= 10 x 1000 x (25 x 4)
= 10 x 1000 x 100
= 10000 x 100
= 1000000

8 x 5 x 125 x 4 x 2 x 25

= (8 x 125) x (5 x 2) x (4 x 25)

= 1000 x 10 x 100

= 1.000.000

tick cho mk nhé~!!

chúc bạn học tốt!!!!❤
