Use the sqaure root property to solve the equation.

7x^2-4=0

x^2 = 4/7

x = +/- sqrt (4/7) = +/- 2 sqrt(1/7)
= +/- (2/7) sqrt(7)

7x^2-4

x^2-4=1/7
x^-2=1/7
1/x^2=1/7
[1/x]^2=1/7
1/x=1/sqrt7
x=sqrt7

To solve the equation 7x^2 - 4 = 0 using the square root property, we want to isolate the variable on one side of the equation and then take the square root of both sides.

First, add 4 to both sides of the equation to move the constant term:
7x^2 = 4

Then, divide both sides of the equation by 7 to isolate the x^2 term:
x^2 = 4/7

Now, we can take the square root of both sides to solve for x:
√(x^2) = √(4/7)

Remember that when we take the square root, we need to consider both the positive and negative square root.

√(x^2) = ±√(4/7)

Simplifying the square root of 4 gives us:
x = ±(2/√7)

Therefore, the solutions to the equation 7x^2 - 4 = 0 using the square root property are:
x = 2/√7 or x = -2/√7
