how do u divide exponents oh great wizards send help now pls class is \stupid and i hate math help pls
If you have adivision expression that has the same base in both the numerator and the denominator, subtract the exponents.
Examples:
1) x13 / x5 = x13 - 5 = x8
2) x7 / x7 = x7 - 7 = x0 = 1
3) x3 / x7 = x3 - 7 = x-4 = 1 / x4
4) ( 4x3y5z ) / ( 8x4y3z7 ) = ( 4/8 )( x3 / x4 )( y5 / y3 )( z / z7 ) = ( 1/2 )( x3 - 4 )( y5 - 3 )( z1 - 7 ) = (1/2)( x-1 y2 z-6 )
= (1/2)·y2 / ( xz6 ) = y2 / ( 2xz6 )
5) (12x2yz5 ) / ( 51x3ab ) = ( 12/51 )( x2 / x3 )( yz5 ) / ( ab ) = ( 4yz5 ) / ( 17xab )
