(a) 2187?

Answer 1

Answer:

Step-by-step explanation:

to find the smallest number that must be multiplied with 2187 to mae it a perfect square , first prime factorise it

3 | 2187

3 | 729

3 | 243

3 | 81

3 | 27

3 | 9

3 | 3

    1                       so 2187 = 3x3x3x3x3x3x3

                            to make it a perfect square = (3)x2187 = 3x3x3x3x3x3x3x(3)

Therefore, the smallest number that must be multiplied with 2187 to make it a perfect square = 3
