tolong bantu mohon sekali nomor 13, 14 , 15 kalau bisa semuanya alhamdulillah kalau bisa cuman 1 atau 2 nggak papa

13) 32^-3/5 + 125^-⅔

= (2^5)^-3/5 + (5³)^-⅔

= 2-³ + 5-²

= ( 1/2³ ) + ( 1/5²)

= 1/8 + 1/25

= 25 + 8
--------------
200

= 33
--------
200

( D )


14) 36p²q^-5r
---------------------
( 3pq-¹ )³

= 36p²q^-5r
-------------------
27p³q-³

= 36p²q³r
---------------
27p³q^5

= ( 9p²q³ )( 4r )
-----------------------
( 9p²q³ )( 3pq² )

= 4r
--------
3pq²

( A )


15) 5a²
------------
2b-⁴

= 5a²b⁴
------------
2

= ( 5/2 )a²b⁴

( A )

13. D
maaf kalau salah ^ _____^
