(13) Find the smallest number by which 252 must be multiplied to get a perfect
square. Also, find the square root the perfect square so obtained.
(14) Find the smallest number by which 2925 must be divided to obtain a perfect
square. Also find the square root of the perfect square so obtained.

Step-by-step explanation:

13) 252 should be multiplied by 7 the answer is 1764 which is a perfect square

The square root of 1764 is 42

14) we will divide 2925 by 13 the answer will be 225 which is a perfect square

The square root of 225 is 15

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
