i) Find the value of x, if 10000 x = (9982)2 – (18)2.
i) By using suitable identity, evaluate x2 + if x – 1= 5.​

Answer 1

Answer:

i)1.9928

ii)36

Step-by-step explanation:

10000 x =[9982]2-[18]2

              =19964-36

              =19928

=> x =19928/10000

       =1.9928

ii) x-1 =5

=> x = 5+1

       = 6

=> x square = 6^{2}

                   = 36
