Practical Examples of the 98 Square Root
To better understand the 98 square root, let’s look at some practical examples where it is applied.
Example 1: Pythagorean Theorem
The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse © is equal to the sum of the squares of the lengths of the other two sides (a and b). The formula is:
c² = a² + b²
To find the length of the hypotenuse, you can take the 98 square root of the sum of the squares of the other two sides. For example, if a = 7 and b = 5, then:
c² = 7² + 5² = 49 + 25 = 74
To find c, take the 98 square root of 74:
c = √74 ≈ 8.602
Example 2: Simple Pendulum
The period of a simple pendulum is the time it takes to complete one full cycle (back and forth). The formula for the period (T) of a simple pendulum is:
T = 2π√(L/g)
where L is the length of the pendulum and g is the acceleration due to gravity. If L = 98 cm and g = 9.8 m/s², then:
T = 2π√(98/9.8) = 2π√10 ≈ 19.94 seconds
