a) 500 + 500 + 500 = x

1500 = x

=> x = 1500

b) x + x + x = 15

3. x = 15

x = 15 : 3

x = 5

c) 50 + 50 = x . 50

100 = x . 50

100 : 50 = x

2 = x

=> x = 2

x + 500 = 500 + 500

x + 500 = 1000

x = 1000 - 500

x = 500

x + 500 = 500 + 500

x + 500 = 1000

         x = 1000 - 500

Ai k mình mình k lại cho

a) x . x . x = 125

x³ =125

x³ = 5³

= > x = 5

b) ( x + 500 ) = 1000 - 200 . 2

x + 500 = 1000 - 400

x + 500 = 600

x = 600 - 500

x = 100

c) [( x + 10 ) . 100 ] = 500 + 500 . 10

( x + 10 ) . 100 = 500 + 5000

( x + 10 ) . 100 = 5500

x + 10 = 5500 : 100

x + 10 = 55

x = 55 - 10

x = 45

500 × 4 × 2 × 25 - 500 × 3 × 2 × 30

= 500 × (4 × 2 × 25) - 500 × (3 × 2 × 30)

= 500 × 200 - 500 × 180

= 500 × (200 - 180)

= 500 × 20

= 10000

x + 200 = 500 + 500

x + 200 = 1000

x           = 1000 - 200

x          = 800

Vậy x = 800

x + 200 = 500 + 500

x + 200 = 1000

x          = 1000 - 200

x          = 800

x + 200 = 500 + 500

x + 200 = 1000

          x = 1000 - 200

           x = 800

x+500=600

x=600-500

x=100
