Can you please tell me the ans with the process

 d) 6   e) 10     g) 900

Step-by-step explanation:

d)

98² = 9604

9610 - 9604 = 6

e)

54² = 2916

2916 - 2906 = 10

g)              10            12          15

                 ∧             ∧            ∧

               2·5         2·2·3       3·5

The Perfect square is: 2² · 5² · 3² = 30²

30² = 900

zero

step-by-step explanation:

f(2)= x-2
