Question: ` .009 ÷ ? = .01`
A
`9`

B
`.9`

C
`.09`

D
`0.0009`

Note: Let, `.009/x` `= .01`. Then , `x= .009/.01` `= .9/1` `= .9`.

A
` 60.606`

B
` 66.06`

C
` .60606`

Question: The value of `(3.75 xx 3.75 - 2 xx 3.75 + 2.75 xx 2.75)` is :
A
`1`

B
`1.75`

C
`4.75`

D
`6.50`

Note: Given Exp : `= (3.75)^2 - 2 xx 3.75 xx 2.75 + (2.75)^2` `=(a^2 - 2ab + b^2)` `= (a-b)^2` `= (3.75 - 2.75)^2` `= 1^2` `= 1`.

Question: Expression `(11.98 xx 11.98 + 11.98 xx x + .02 xx .02)`will be perfect square for equal to :
A
` .02`

B
` .2`

C
` .04`

D
` 0.4`

Note: Given Exp : `= (11.98)^2 + (.02)^2 + 11.98 xx x` For the given expession to be a perfect square , we must have `11.98 xx x` `= 2 xx 11.98 xx .02` 0r x`=.04`

Question: The value of ` (2.75 xx 2.75 xx 2.75 -2.25 xx 2.25 xx 2.25)/(2.75 xx 2.75 + 2.75 xx 2.25 + 2.25 + 2.25)` is :
A
`0.30`

B
`0.50`

C
` 3`

D
`5`

Note: Given Exp : `((2.75)^3 - (2.25)^3)/((2.75)^2 + 2.75 xx 2.75 + ( 2.25)^2)` `= ((a^3 - b^3)/(a^2 + ab + b^2))` `= (a - b)` `= (2.75 - 2.25)` `= 0.50`

A
`.538`

B
`5.38`

C
`.0538`

D
`53.8`

Note: Given Exp : `((8.94)^3 - (3.65)^3)/((8.94)^2 + 8.94 xx 3.56 + (3.56)^2)` `=((a^3 -b^3)/(a^2 + ab + b^2))` `= (a - b)` `= (8.94 - 3.56)` `= 5.38`
