Find the real roots of the eqution
16x2(squared) = 81
16x^2 = 81
x^2 = 81/16
x = ± 9/4
Yes I got it right! Thanks
To find the real roots of the equation 16x^2 = 81, you can follow the steps below:
Step 1: Start with the given equation: 16x^2 = 81.
Step 2: Divide both sides of the equation by 16 to isolate the variable x: (16x^2)/16 = 81/16.
Step 3: Simplify: x^2 = 81/16.
Step 4: Take the square root of both sides of the equation to solve for x: sqrt(x^2) = sqrt(81/16).
Step 5: Simplify: x = ±(sqrt(81)/sqrt(16)).
Step 6: Further simplify: x = ±(9/4).
Step 7: The real roots of the equation are x = 9/4 and x = -9/4.
Therefore, the real roots of the equation 16x^2 = 81 are x = 9/4 and x = -9/4.
