How to find a CUBE ROOT of number

13824
Step 1: Now to find the unit place of the cube root always remember the following points
1.If the Last digit of a cube root is 8 than the unit digit will be 2.
2.If the Last digit of a cube root is 2 than the unit digit will be 8.
3.If the Last digit of a cube root is 3 than the unit digit will be 7.
4.If the Last digit of a cube root is 7 than the unit digit will be 3.
5.If the Last digit of a cube root is other than 2,3,7,8 than put the same number as the unit digit.
Now the unit digit will be 4

Step 2: Now strike the last 3 digits of the given number.
13824

Step 3: Now find the nearest square of the first 2 digit from the left
Now the nearest cube is 8

Step 4: now 8 is the cube root of 2
Therefore the ten’s place digit is 2
So the answer will be 24

Useful maths formula for competitive exam

Algebra:

● Laws of Indices:

(i) a^m ∙ aⁿ = a^{m + n}

(ii) a^m/aⁿ

(iii) (a^m)ⁿ = a^mn

(iv) a⁰ = 1 (a ≠ 0).

(v) a^{- n} = 1/aⁿ

(vi) ⁿ√a^m = a^m/n

(vii) (ab)^m = a^m ∙ bⁿ.

(viii) (a/b) ^m = a^m/bⁿ

(ix) If a^m = b^m (m ≠ 0), then a = b.

(x) If a^m = aⁿ then m = n.

● Arithmetical Progression (A.P.):

(i) The general form of an A. P. is a, a + d, a + 2d, a+3d,.....

where a is the first term and d, the common difference of the A.P.

(ii) The nth term of the above A.P. is t_n = a + (n - 1)d.

(iii) The sum of first n terns of the above A.P. is s = n/2 (a + l) = (No. of terms/2)[1st term + last term] or, S = ⁿ/₂ [2a + (n - 1) d]

(iv) The arithmetic mean between two given numbers a and b is (a + b)/2.

(v) 1 + 2 + 3 + ...... + n = [n(n + 1)]/2.

(vi) 1² + 2² + 3² +……………. + n² = [n(n+ 1)(2n+ 1)]/6.

(vii) 1³ + 2³ + 3³ + . . . . + n³ = [{n(n + 1)}/2 ]².

Easy Maths Tricks with fun

Now, Learn Maths with fun by your fingers. If you have problems remembering the multiplication table of 9, try this finger math trick:

• Open both of your hands, extending your fingers, in front of you.
• To multiply 9 by 5, fold down your fifth finger from the left.
• Get the answer to 9 by 5 by counting your fingers on either side of the bent finger and combining them: 4 and 5 makes 45.
• To multiply 9 by 6, fold down your sixth finger from the left, and on.
• Get the answer to 9 by 6 by counting your fingers on either side of the bent finger and combining them: 5 and 4 makes 54.

Now you can quickly remember the multiplication table of 9 all the way up to 9 times 10 with fun.

Play the same for the below multiplications

1 × 9 = ?

2 × 9 = ?

3 × 9 = ?
