find the square number by which 1800 must be multiplied so that it becomes a perfect square .also find the square root of the perfect square so obtained​

Answer»

Answer:

60

Step-by-step explanation:

1800 = 18x100

= 3x6x2²x5²

= 2³x3²x5²

To BECOME a perfect square it needs to be multiplied by 2 to MAKE it's power even.

So,

2x1800 = 2⁴x3²x5²

Now, Square root is,

= √ (2⁴x3²x5²)

= 2²x3x5

= 60

So if we multiply 1800 by 2, we get a perfect square, 3600 WHOSE root is 60.
