Question

. Find the square root of 1764 by prime factorisation.​

Answer 1

Answer:

42

Step-by-step explanation:

First off, we need to prime factorize the number 1764

1764 = 2 x 2 x 3 x 3 x 7 x 7

Now since we are finding square root of 1764, we can equate as follows

√1764 = √2x2x3x3x7x7

Group double numbers and cancel them out of the root in R.H.S

√1764 = 2x3x7√1 (since √1 is 1 and any number multiplied is 1, we can cancel it out)

√1762 = 42//
