2. Tulislah dalam bentuk yang paling sederhana
a. 16 / 4⊃2; x 2⊃3;
Jawaban:
= 16 / 4⊃2; x 2⊃3;
= (2 ) / (2⊃2;)⊃2; x 2⊃3;
= 2⊃2; / 2 x 2⊃3;
= 2⊃2; /2
= 2⊃2; -
= 2⊃1;⊃3;
b. 9 /3 : 3⊃2;/27⊃2;
Jawaban:
= 9 /3 : 3⊃2;/27⊃2;
= (3⊃2;) /3 : 3⊃2;/(3⊃3;)⊃2;
= 3 /3 : 3⊃2;/3
= 3 - : 3⊃2;-
= 3⊃3; - 3-
= 3⊃3;-(- )
= 3
c. 16 /4 x 32⊃2;/8⊃3;
Jawaban:
= 16 /4 x 32⊃2;/8⊃3;
= (2 ) /(2⊃2;) x (2 )⊃2;/(2⊃3;)⊃3;
= 2⊃1; /2⊃1; x 2⊃1; /2
= 2⊃1; -⊃1; x 2⊃1; -
= 2 x 2⊃1;
= 2 +⊃1;
= 2
d. 25⊃3; x 125⊃2; / 5⊃2; x 625⊃2;
Jawaban:
= 25⊃3; x 125⊃2; / 5⊃2; x 625⊃2;
= (5⊃2;)⊃3; x (5⊃3;)⊃2; / (5⊃2;) x (5 )⊃2;
= 5 x 5 / 5⊃2; x 5
= 5⊃1;⊃2;/5⊃1;
= 5⊃1;⊃2;-⊃1;
= 5⊃2;
