Quiz

1.) 5³ = ...

2.) 3x + 2 = 8
x = ...

3.) 4x + 0 = 100
x = ...
​

Penjelasan dengan langkah-langkah:

Jawab (1)

• 5³
• = 5 × 5 × 5
• = 25 × 5
• = 25 + 25 + 25 + 25 + 25
• = 50 + 25 + 25 + 25
• = 75 + 25 + 25
• = 100 + 25
• = 125

Jawab (2)

• 3x + 2 = 8
• 3x = 8 - 2
• 3x = 6
• x = 6/3
• x = 2

Jawab (3)

• 4x + 0 = 100
• 4x = 100 - 0
• 4x = 100
• x = 100/4
• x = 25

Penjelasan dengan langkah-langkah:

1) 5³ = 5² x 5

5³ = 25 x 5

5³ = 25 + 25 + 25 + 25 + 25

5³ = 50 + 50 + 25

5³ = 100 + 25

5³ = 125

2) 3x + 2 = 8

3x + 2 –2 = 8 –2

3x + 0 = 6

3x = 6

x = 6/3

x = 2

3) 4x + 0 = 100 [ dibagi 4)

4x/4 = 100/4

x = 25
