Step-by-step explanation:

  • a. √x - 3 = 0 ⇒ √x = 3 ⇒ x = 3² ⇒ x = 9
  • b. √x = -10,

no solution as √x is a positive value

  • c. √x+1=0 ⇒ √x = - 1,

no solution as √x is a positive value

  • d. √x = 0.1 ⇒  x = 0.1² ⇒ x = 0.01

#1

  • √x-3=0
  • x-3=0
  • x=3

If square root is over x only x=3²=9

#2

No solutions as -10 is <0

#3

  • √x+1=0
  • x+1=0
  • x=-1

If root is over x only then no solutions

#4

√x=0.1

x=0.01
