4x56x7SolutionGiven that 4 x5 6 x7 2 3 x 5 7 sin

4x^-5/6x^-7

Given that

( 4 x^-5 ) / ( 6 x^-7 ) = ( 2 / 3 ) ( x ^{-5- (-7)} ) [ since, x^a / x^b = x^{a-b ]}

= ( 2 / 3 ) ( x ^{-5 + 7} )

= ( 2 / 3 ) ( x² )

Therefore,

( 4 x^-5 ) / ( 6 x^-7 ) = ( 2 / 3 ) ( x² )

4x^-5/6x^-7SolutionGiven that ( 4 x-5 ) / ( 6 x-7 ) = ( 2 / 3 ) ( x -5- (-7) ) [ since, xa / xb = xa-b ] = ( 2 / 3 ) ( x -5 + 7 ) = ( 2 / 3 ) ( x2 ) Therefore,
