Step-by-step explanation:
Given expression is x⁴-kx²+4 =0
x−2 is a factor of the given expression.
So, x=2
Substitute in the equation, we get
2⁴-k(2)²+4
⇒16+4k+4=0
⇒4k=−20
⇒k=−5

To get the 0.12 to repeat, the trick is to subtract 1 from the denominator

Then reduce the fraction.

now add the 3 to get
Answer:
Step-by-step explanation:
We will squared each, we will find
49/9 5 6.25 8 then the correct order
Square root 5
2 1/3
2.5
Square root 8
To make the exponent rational, for square root use 1/2. To wit:
10^(1/2)
Answer:

Step-by-step explanation:
area of square = side x side
thus, each side = square root of area
= 6
= 6
