To simplify the expression \( 6 u^{-1} \cdot 10 u^{-1} \cdot 6 u^{5} \), start by multiplying the coefficients together. \( 6 \cdot 10 \cdot 6 = 360 \). Next, combine the exponents of \( u \): \( u^{-1} \cdot u^{-1} \cdot u^{5} = u^{-1-1+5} = u^{3} \). Thus, the simplified expression is \( 360 u^{3} \). 360 u^{3}
