Answer 1

• 1) 64, 2) 65536, 3) 5

--------------------------------

Solve each equation.

1)

• 
  `3\sqrt[3]{x} =12`
• 
  `\sqrt[3]{x} =4`
• 
  `x = 4^3=64`

2)

• 
  `\sqrt[3]{4x} +3=67`
• 
  `\sqrt[3]{4x} =64`
• 
  `4x=64^3`
• 
  `4x=262144`
• 
  `x=262144/4`
• 
  `x=65536`

3)

• 
  `\sqrt[3]{5x+2} -3=0`
• 
  `\sqrt[3]{5x+2}=3`
• 
  `5x+2=3^3`
• 
  `5x+2=27`
• 
  `5x=25`
• 
  `x=5`
