a. 13

b. (483+17) (483-17)

500*466

233000....

Answer 2

Step-by-step explanation:

on squring both sides

(a+b)² = (5)²

a²+ b²+2ab = 25

ab=6 given in question

so a² + b² + 2(6) = 25

a² + b² = 25 -18

a²+b² = 7

b by using property of a²-b² = (a-b) (a+b)

(483)²-(17)²= (483-17)-(48e+17)

= (466)(500)

= 233000
