This is a question from MGMAT book:
Find the square root of 72
They simplify the square root down to the prime numbers, making it the sq. rt of 3*3*2*2*2. Combining factors: you get the sq root of 9 * sq rt of 4 * sq 2. The answer is then: 3 *2 * sq rt 2 = 6 sq rt 2
I did it a different way, and got a different answer. Is this correct or incorrect:
Sq rt of 72 = sq rt of 9 * sq rt of 8 = 3 sq rt of 8
Is this right?
