Explanation

√15129 = 123, which has 3 digits.

So, the number of digits in the square root of 15129 is 3.

Explanation

In negative fractions, the greater the denominator (for the same numerator), the closer the fraction is to zero, making it larger.

Comparing:

• -1/3 = -0.333
• -2/3 = -0.666
• -4/9 = -0.444
• -5/6 = -0.833

-1/3 is the greatest among them as it is closest to zero.

Explanation

When 5/3 is divided, it gives 1.666..., where 6 repeats infinitely.

Since the decimal never ends but follows a repeating pattern, it is non-terminating and recurring.

Explanation

To find (A ∪ B)':

First, find A ∪ B:

A ∪ B = {2, 3, 4} ∪ {1, 3, 5}

= {1, 2, 3, 4, 5}

Now, find the complement of A ∪ B:

(A ∪ B)' = U - (A ∪ B)

= {1, 2, 3, 4, 5} - {1, 2, 3, 4, 5}

= {}

Explanation

To find the value of k:

Rearrange the equation:

6 = 4.8 / k

Multiply both sides by k:

6k = 4.8

Now, divide by 6:

k = 4.8 / 6

k = 0.8
