Answer:

(x + 2)² = 8

Step-by-step explanation:

To complete the square, write the equation standard form.

-4 + 4x + x² = 0

x² + 4x - 4 = 0

Take the middle term 4x and divide the coefficient in 2 and square it. Here it is 4/2 = 2. 2² = 4. Add 4 to both sides.

x² + 4x + 4 - 4 = 0 + 4

(x + 2)² - 4 = 4

(x + 2)² = 8

Which of the following is the radical expression of a to the four ninths power ?
LuckyWell [14K]

Given expression in exponential form : a^{\frac{4}{9} }.

We need to convert it into radical form.

<em>Please note: When we convert an exponential to radical form, the top number goes in the exponent of the term and bottom number of the fraction goes in the radical sign to make it nth radical.</em>

We can apply following rule:

(a)^{\frac{m}{n}}= \sqrt[n]{x^m}.

Therefore,

a^{\frac{4}{9} }= \sqrt[9]{a^4}.

Therefore, correct option is : D. ninth root of a to the fourth power.

The sides of a square are 2^4/9 inches long. what is the area of the square?
bagirrra123 [75]
The Area of the square is (side)^2

side is given to be 2^(4/9)
SO,
side^2  = [2^(4/9)]^2 = 2^(4/9 * 2) = 2^(8/9)
so the area of square is 2^(8/9) sq. inches.
