Verified answer

Jawaban:

1) a^7

2) m^2 n^10

3) 8 b^3 / a^3

4) 8 a b^2

Penjelasan dengan langkah-langkah:

1. (a^-3/a^4)^-1 = (a^-3-4)^-1

= (a^-7)^-1

= a^-7×(-1)

= a^7

2. 8m^5 n^4 / (2 m n^-2)^3

= 8 m^5 n^4 / (2^3 m^3 (n^-2)^3

= 8 m^5 n^4 / (8 m^3 n^-6)

= m^5 n^4 / (m^3 n^-6)

= (m^5-3) (n^4-(-6))

= m^2 n^10

3. (2 a^5 b / 16 a^2 b^4)^-1

= (2 a^5-2 b / 16 b^4)^-1

= (2 a^3 b / 16 b^4)^-1

= (2 a^3 / 16 b^4-1)^-1

= (2 a^3 / 16 b^3)^-1

= (a^3 / 8 b^3)^-1

= 8 b^3 / a^3

4. (8 a^-6 b^3)^1/3 / (2^4 a^6 b^2)^-1/2

= 8^1/3 (a^-6)^1/3 (b^3)^1/3 / (2^4)^-1/2 (a^6)^-1/2

(b^2)^-1/2

= 8^1/3 a^-2 b / 2^-2 a^-3 b^-1

= (2^3)^1/3 a^-2 b / 2^-2 a^-3 b^-1

= 2 a^-2 b / 2^-2 a^-3 b^-1

= 2 a^-2-(-3) b^1-(-1) / 2^-2

= 2 a b^2 / 2^-2

= 2^1-(-2) a b^2

= 2^3 a b^2

= 8 a b^2
