How Make Simplification Easy

Dear Frnds

We already discuss Easy calculations Tricks, Now understand how solve questions in examination related Simplificaton—

BO-DMAS Rules

B- Brackets in order (){}[]

O- OF

D- DIVISION

M- MULTIPLICATION

A- ADDITION

S- SUBSTRACTION

Example —

1÷[1+1÷{1+1÷(1+1÷3)}]

Solution –

Step1-(1+1÷3)=(1+1/3)

Stet2- {1+1÷(1+1÷3)}={1+1÷4/3}
                                  ={1+1×3/4}
                                  ={1+3/4}
                                  ={7/4}

Step3-  [1+1÷{1+1÷(1+1÷3)}]
            = [1+1÷{7/4}]

           = [1+1÷7/4]
           = [1+1×4/7]
            =[1+4/7]
             =[11/7]
Step 4-

1÷[1+1÷{1+1÷(1+1÷3)}]

=1÷[11/7]
=1×7/11
=7/11(‘-‘)

Others Example :

Q2- 888×88×8
Solution –

888×88×8=8*111×8*11×8*1
                =8³×111*11
                 =512×1221
                  =625152(‘-‘)

Trick -If numbers increase or decrease in a sequence then-

Highest numbers total digit count- here 3

Now number of digit -here 8

Now we find . 8³ and write 111(3digit)×11(decrease order)

So—- 888*88*8=8³*111*11*1
                          =625152

Q3 Find Value of √72+√72+√72+..…°~°

Solution : First find out the factor of no Whose difference is 1

Here72=9×8

Highest no.is your answer…

So. 9 is answer (‘-‘)
