Question

please I need the method how u did it too​

Answer 1

1)15.01²

= 15.01 * 15.01  

15.01

*15.01

_________

    1501

 0000*

7505**

1501***

_________

225.3001

___________

So, 15.01² = 225.3001

2)√81.009

9)81.009 (9.004.......

  -81

--------------------

180)000

        -  0

-------------------------------

1800)       0900

                 -0

----------------------------------

18004)          90000

                   - 72016

----------------------------------

                     17984

---------------------------------------

So, √81.001 = 9.004... consider it as 9.004

3) 15.01²  + 9.004 * 32

= 225.3001  + 9.004 * 32

By BODMAS we should first multiply and then add.

= 225.3001 + 288.128

= 513.4281

15.01²  + 9.04 * 32 = 513.4281
