b. 7935
c. 1575

Answer 1

hi friend : 
a  768 : prime factors = 2*2*2*2*2*2*2*2*3pairs = 2*2*2*2*since 2 is unpaired so 768 should be multiplied by 768 768 * 3 = 2304 and square root of it is 48
b 7935 : prime factors are : 3*5*23*23since  3*5 is unpaired so 7935 should be multiplied by 157935*15=119025 and square root of 119025is 345
c 1575 = prime factors : 3*3*5*5*7since 7 is unpaired so 1575 should be multiplied by 7 = 1575*7=11025square root of 11025 is 105
