The root of *
x^2 = 16 are

Option 1 [ +4 ]
+4
(0,4)
-4

The roots of the equation are

Step-by-step explanation:

First rewrite the expression

That's

x² - 16

16 = 4²

So we have

x² - 4² = 0

Using the identity

Rewrite the expression

So we have

x² - 4² = 0 is

( x + 4)( x - 4) = 0

x + 4 = 0 x - 4 = 0

x = - 4 x = 4

The roots of the equation are

- 4 and 4

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

i think it is 18
