6x^{-2}\times \frac{1}{2^{2}\left(x^{-3}\right)^{2}}
Expand \left(2x^{-3}\right)^{2}.
6x^{-2}\times \frac{1}{2^{2}x^{-6}}
To raise a power to another power, multiply the exponents. Multiply -3 and 2 to get -6.
6x^{-2}\times \frac{1}{4x^{-6}}
Calculate 2 to the power of 2 and get 4.
\frac{6}{4x^{-6}}x^{-2}
Express 6\times \frac{1}{4x^{-6}} as a single fraction.
\frac{6x^{-2}}{4x^{-6}}
Express \frac{6}{4x^{-6}}x^{-2} as a single fraction.
\frac{3x^{-2}}{2x^{-6}}
Cancel out 2 in both numerator and denominator.
\frac{3x^{4}}{2}
To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent.
