x= 344×9/7

Answer 2

Answer:

Required answer is 730

Explanation:

Given, 7:344::9:?

This is a problem of General Inteligence.

If we notice all given digit then we can see that all numbers here maintain a sequence.

Here,

$7:344 \\ = 7:(343 + 1) \\ = 7:( {7}^{3} + 1)$

So we can say if x is a number then $x:( {x}^{3} + 1)$

Here number is 9.

So,

$9:( {9}^{3} + 1) \\ = 9:(729 + 1) \\ = 9:730$

Therefore required answer is 730.

General intelligence is a part of Mathematics.

Some important Mathematics formulas:

${(x + y)}^{2} = {x}^{2} + 2xy + {y}^{2} \\ {(x - y)}^{2} = {x}^{2} - 2xy + {y}^{2} \\ {(x + y)}^{3} = {x}^{3} + 3 {x}^{2} y + 3x {y}^{2} + {y}^{3} \\ {(x - y)}^{3} = {x}^{3} - 3 {x}^{2} y + 3x {y}^{2} - {y}^{3} \\ {x}^{3} + {y}^{3} = {(x + y)}^{3} - 3xy(x + y) \\ {x}^{3} - {y}^{3} = {(x - y)}^{3} + 3xy(x - y) \\ {x}^{2} - {y}^{2} = (x + y)(x - y) \\ {x}^{2} + {y}^{2} = {(x - y)}^{2} + 2xy \\ {x}^{2} - {y}^{2} = {(x + y)}^{2} - 2xy \\ {x}^{3} - {y}^{3} = (x - y)( {x}^{2} + xy + {y}^{2} ) \\ {x}^{3} + {y}^{3} = (x - + y)( {x}^{2} - xy + {y}^{2} )$
