1)  

 Simplify   :   53 + 212 + 1024

Answer: 94


SOLUTION 1 :

=     53 + 212 + 1024  

LCM of 3 12 .24 is  24

=  [(5x8) +(2x2) + (10x1)] / 24

= (40+4+10)24

 = (54)24

 = 94

 



2)  

 Simplify   :   23 + 512 + 324

Answer: 2924


SOLUTION 1 :

=     23 + 512 + 324  

LCM of 3 12 .24 is  24

=  [(2x8) +(5x2) + (3x1)] / 24

= (16+10+3)24

 = (29)24

 = 2924

 



3)
