Find the value of given expression


​

√{3625×3625}=√3625²=3625

3625

Step-by-step explanation:

Square root is opposite of the power of 2.

In this case, note that the numbers within the root are the same (3625):

3625 x 3625 = 3625².

The square root and the power of 2 will cancel out:

√(3625²) = 3625

3625 is your answer.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

eight hundred an fifty one point four hundred and fifteen
