Answer:


3x^7{\cdot} (4x^(-5))^2=(48)/(x^3)

Explanation:

We need to simplify the given expression :


3x^7{\cdot} (4x^(-5))^2

Use property :
x^(-a)=(1)/(x^a)


3x^7{\cdot} ((4)/(x^5))^2\\ =3x^7{\cdot} (16)/(x^(10))\ \ [\because (x^a)^b=x^(a* b)]\\\\=(48)/(x^3)

So, the simplified form of the given expression is
(48)/(x^3)
