Question

kak bantu mtk saya kak, cara nya sama seperti di contoh ya kak...


1. 25mn² : 5mn⁴
2. 15xy : 3xy
3. 15x²y² : 5xy³
4. 12a⁵b⁷ : 2ab
5. 12ab : 6ab⁵


kak bantu kakak, cara nya sama kayak di gambar ya kakakk​

Answer 1

Materi : Bentuk Akar dan Pangkat

Soal Nomor 1

25mn² ÷ 5mn⁴

= ( 25/5 )( m/m )( n²/n⁴ )

= ( 5 )( 1 )( 1/n⁴-² )

= ( 5 )( 1/n² )

= 5/n²

Soal Nomor 2

15xy ÷ 3xy

= ( 15/3 )( x/x )( y/y )

= ( 5 )( 1 )( 1 )

= 5

Soal Nomor 3

15x²y² ÷ 5xy³

= ( 15/5 )( x²/x )( y²/y³ )

= ( 3 )( x²-¹ )( 1/y³-² )

= ( 3 )( x )( 1/y )

= 3x/y

Soal Nomor 4

12a⁵b⁷ ÷ 2ab

= ( 12/2 )( a⁵/a )( b⁷/b )

= ( 6 )( a⁵-¹ )( b⁷-¹ )

= ( 6 )( a⁴ )( b⁶ )

= 6a⁴b⁶

Soal Nomor 5

12ab ÷ 6ab⁵

= ( 12/6 )( a/a )( b/b⁵ )

= ( 2 )( 1 )( 1/b⁵-¹ )

= ( 2 )( 1/b⁴ )

= 2/b⁴

Semoga bisa membantu
