Tricks to Solve the Approximations

Dear students, to solve the large appear type approximation problems rapidly you lot must retrieve few algebraic formulas which nosotros accept enlisted below.

Important formula of algebra:

1. (a+b)^2 = a^2+b^2+2ab

2. (a-b)^2 = a^2+b^2-2ab

3. (a+b)^2 = (a-b)^2+4ab

4. (a-b)^2 = (a+b)^2-4ab

5. (a+b)^3 = a^3+b^3+3ab(a+b)

6. (a-b)^3 = a^3-b^3-3ab(a-b)

7. a^3+b^3 = (a+b)(a^2-ab+b^2)

8. a^3-b^3 = (a-b)(a^2+ab+b^2)

9. (a+b+c)^2 = a^2+b^2+c^2+2(ab+bc+ca)

10. a^3+b^3+c^3-3abc=(a+b+c)(a^2+b^2+c^2-ab-bc-ca)

11. If a+b+c=0 together with thus a^3+b^3+c^3=3abc

Shortcuts Solution of the Questions given below:

Q1. (299.12 + 312.01)^2 / (299.12 + 312.01)

Shortcut Solution: Apply 1st formula:

(299.12 + 312.01)^2 / (299.12 + 312.01)

=(299.12 + 312.01)((299.12 + 312.01)) / (299.12 + 312.01)

=(299.12 + 312.01)

=299+312

=611

Q2. (998.10)^3 + (888.10 )^3 / (998.10)^2+(888.10)^2-(998.10*888.10)

Shortcut Solution: Apply seventh formula:

(998.10)^3 + (888.10 )^3 / (998.10)^2+(888.10)^2-998.10*888.10

=(998.10+888.10 )(998.10)^2+(888.10)^2-998.10*888.10) / (998.10)^2+(888.10)^2-(998.10*888.10)

=998.10+888.10

=998+888

=1886

Q3. (1.33 - 1.22)^2 / (1.33^2 - 1.33*1.22 + 1.22^2)

Shortcut Solution: Apply 2d formula:

(1.33 - 1.22)^2 / (1.33^2 - 1.33*1.22 + 1.22^2)

= (1.33^2 - 1.33*1.22 + 1.22^2) / (1.33^2 - 1.33*1.22 + 1.22^2)

=1

Q4. (11.11)^3+(22.22)^3+(33.33)^3-3*11.11*22.22*33.33 / (11.11)^2+(22.22)^2+(33.33)^2-11.11*22.22-22.22*33.33-33.33*11.11

Shortcut Solution: Apply tenth formula:

(11.11)^3+(22.22)^3+(33.33)^3-3*11.11*22.22*33.33 / (11.11)^2+(22.22)^2+(33.33)^2-11.11*22.22-22.22*33.33-33.33*11.11

=(11.11+22.22+33.33)(11.11)^2+(22.22)^2+(33.33)^2-11.11*22.22-22.22*33.33-33.33*11.11 / (11.11)^2+(22.22)^2+(33.33)^2-11.11*22.22-22.22*33.33-33.33*11.11

= (11.11+22.22+33.33)

=11+22+33

=66

Q5. (5.14)^3 - (3.12)^3 / (5.14)^2+5.14*3.12+(3.12)^2

Shortcut Solution: Apply eighth formula:

(5.14)^3 - (3.12)^3 / (5.14)^2+5.14*3.12+(3.12)^2

= (5.14 - 3.12)(5.14)^2+5.14*3.12+(3.12)^2 / (5.14)^2+5.14*3.12+(3.12)^2

=5.14-3.12

=5-3

=2
