✔ 最佳答案
The rule for exponents is: (a^b)^c = a^(bc)So basically you "distribute" the exponent through (since they are all being multiplied):
5^3 * (m^6)^3 * (n^5)^3
= 125 * m^(6*3) * n^(5*3)
= 125 * m^18 * n^15
Answer:
125 m^18 n^15

(5m^6n^5)^3
= (5^3)(m^6)^3(n^5)^3
= [125][m^(6 * 3)][n^(5 * 3)]
= [125][m^18][n^15]
= 125m^18n^15
= (5^3)(m^6)^3(n^5)^3
= [125][m^(6 * 3)][n^(5 * 3)]
= [125][m^18][n^15]
= 125m^18n^15

[ (5) (m^6) (n^5) ] ³
125 m^18 n^15
125 m^18 n^15

This is equal to:
125m ^(18n^5)
125m ^(18n^5)

(5m^6n^5)^3
= 5 * m^6 * n^5 * 5 * m^6 * n^5 * 5 * m^6 * n^5
= 5*5*5 * m^6*m^6*m^6 * n^5*n*5*n^5
= 125m^18n^15
This is using the rule x^a * x^b = a^(a+b).
= 5 * m^6 * n^5 * 5 * m^6 * n^5 * 5 * m^6 * n^5
= 5*5*5 * m^6*m^6*m^6 * n^5*n*5*n^5
= 125m^18n^15
This is using the rule x^a * x^b = a^(a+b).
