      If unit number would be 8, For example 45968 then how find out square root cause 1-10 all square doesen't have 8 number in the unit number. and also 2,7,3 the numbers would be on unit then how find out square root?

  • @prateekgupta8861

    In ques 12, you make the RHS very complex. We can simply do this👇
    90/? = (√64/729)^(-1/3)
    = (8/27)^(-1/3)
    =(27/8)^(1/3)
    = 3/2
    i.e. 90/?= 3/2
    ?= 60.
    That's it. It's very simple.

    • @asiya504
      @asiya504 4 หลายเดือนก่อน

      Simply (√64/729)^-1/3 = ( √729/64)^1/3 flip the numbers to remove negative sign then √9/4 = 3÷2

  • @pritamsaha86
    @pritamsaha86 4 ปีที่แล้ว +14

    Simply a wonderful way to teach.
    Me just want to add a point. In the problem of square root you just consider the greater than or less than condition to determine the final answer in case of dual conditions. But didn't touch about the "equal to" condition. For example to find square root of 1296. The no whose last digit of square ends with 6 is 4 & 6. The perfect square which is less than 12 is 9 i.e. square of 3. Now 9+3=12. Here the answer is 36. So please add the condition for being equal and it's result.

    Hello sir this channel doing really very good .... I'm impressed...
    A very little bit simplification going wrong, in question number 8 the product of two numbers is 108
    Mistake is in 225-9=216 mentioned as 116.
    This is not to show your mistake it's just how I follow your class
    Thanking you...

      We have to rationalise the given prblm.so so we have to multiply by and devided by the same value with opposite sign .then apply (a+b) (a-b) formula,then you get a^2-b^2 .so roots get cancelled .in the upper portion you have 5+3(1.41.) devide by 7.then you get the answer 1.320
