Find the two square roots of 4

Answers

Answer 1

Answer:

The two square roots of 4 are 2 and -2.

What is square root?

The factor of a number that, when multiplied by itself, yields the original number is known as the square root of the number. Special exponents include squares and square roots. Think about the number 9. When the number 3 is multiplied by itself, the result is 9. This can be expressed as either 3² or 3 × 3.

Given:

The number is 4,

Factorize the number as shown below,

4 = 2 × 2

Calculate the value of the square root of 4 as shown below,

√4 = √(2 × 2)

√4 = ±2

√4 = 2 or -2

Check as:

-2 × -2 = 4

2 × 2 = 4

Thus, the square root of 4 is 2 and -2.

Answer 2

Answer:

Whenever you take the square root of a number you get a negative and a positive result: √ 4 = ± 2 or { − 2 , 2 } − 2 ⋅ − 2 = 4 and 2 × 2 = 4

2X^2-5x+2=0
Quadratic formula

Answers

Answer:

The solutions are $x_(1)=2\ and\ x_(2)=0.5$ .

Step-by-step explanation:

Given:

$2x^(2) -5x+2=0$

Now, to solve by using quadratic formula:

$x=\frac{-b\pm \sqrt{b^(2)-4ac}}{2a}$

Here $a=2,b=-5\ and\ c=2$

$x=\frac{-(-5)\pm \sqrt{(-5)^(2)-4* 2* 2}}{2* 2}$

Now, here we will take either $x=(-(-5)+√(25-16))/(4)$ and then $x=(-(-5)-√(25-16))/(4)$ .

$x=(-(-5)+√(25-16))/(4)$ $x=(-(-5)-√(25-16))/(4)$

$x=(5+√(9))/(4)$ $x=(5-√(9))/(4)$

$x=(5+3)/(4)$ $x=(5-3)/(4)$

$x=(8)/(4)$ $x=(2)/(4)$

$x_(1)=2$ $x_(2)=(1)/(2)=0.5$

Therefore, the solutions are $x_(1)=2\ and\ x_(2)=0.5$ .

__in3

Answers

Well 3*2 = what , = 6 , this means that 6 is the new side length of the new scaled figure.

V = a * a * a . Where a is the side length ,

this means that we now have V = (6)*3 | now simplify .

This should equal 216 says most people | you should at lease get 54

I really hope that I helped you out a lot. Have a nice day.
