Question

4+5-2=33 ,10+12-5=119 ,6+8-3=?

Answer 1

Solution

To find 6 + 8 - 3

Given ,

4 + 5 - 2 = 33

10 + 12 - 5 = 119

From these equations we have

4 + 5 - 2 = 33

$= 4^{2} + 5^{2} - 2^{3}$

= 33

Also,

10 + 12 - 5 = 119

$= 10^{2} + 12^{2} - 5^{3}$

= 100 + 144 - 125

= 119

Using this pattern we can calculate

6 + 8 - 3

$= 6^{2} + 8^{2} - 3^{3}$

= 36 + 64 - 27

= 100 - 27

= 73
