Question

d (2/3*2) . (2/3*3)

e (1/4 ab) . (3/5 ab)

Answer 1

d

( 2/3) * 2/1 =  4/3 ****
( 2/3) * 3/1 =  6/3 ****
4/3 * 6/3 = 24/9 ****resposta
multiplica os numeradores e multiplica os denominadores

e

( 1/4) * (ab/1) =  ( 1 * ab)/ ( 4 * 1 )  = ab/4 ***
( 3/5 ) * ( ab/1) = ( 3 * ab)/ ( 5 * 1) =  3ab/5 ***
( ab/4 ) * ( 3ab)/5 ) = ( ab * 3ab)/ ( 4 * 5 )  = 3a²b²/20 ***
