Question

Is there a value of x that makes each of the following equalities true? If there is, find it.
a. √x-3=0
b. √x=-10
c. √x+1=0
d. √x=0.1

Answer 1

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

Answer 2

#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
