Question

simplified it. help me​

Answer 1

Answer:

You can use calculator to solve it anyway..

But here it uses some simple trick to simplify it

Suppose a = 4.53 - 3.07 , b = 3.07 - 2.15 and c = 2.15 - 4.53

Now put a b c in equations in place of these values

It becomes

a^2/bc + b^2/ca + c^2/ab

Take LCM and simplify

= (a^2 * a + b^2 * b + c^2 *c )/ abc

= a^3 + b^3 + c^3 / abc

Now if you have read that

if a + b + c = 0 then a^3 + b^3 + c^3 = 3abc

then see here

a + b+ c = 4.53 - 3.07 + 3.07 - 2.15 + 2.15 - 4.53 = 0

so we can use it happily and we get

= 3abc / abc

= 3

Now solve it by addition and subtraction and see if it's right or not
