1. Jawaban fatimah3085
1) 16x⁴
------------
2x³
= 8x
2) 6x² + 19x + 15
--------------------------
3x + 5
= (3x + 5)(2x + 3)
--------------------------
( 3x + 5 )
= 2x + 3
3) (8x / 3x) + (3 / 2x)
= (8x • 2x)+(3 • 3x)
----------------------------
( 3x • 2x)
= 16x² + 9x²
------------------
6x²
= 25x²
-----------
6x²
= 25/6
= 4 ¹/6
4) (2a / 3x) • (2x - 6 )/ 12a
= 2a • (2x - 6)
---------------------
3x • 12a
= 2x - 6
-------------
18x
= 2(x - 3)
---------------
2(9x)
= x - 3
----------
9x
