Answer:
(4^-3)(x^-3) y^(18)
or
y^18/ (64 x^3)
Step-by-step explanation:
(4xy^-6)^-3
Distribute the exponent to all terms in the parentheses
(4^-3)(x^-3) (y^-6)^-3
a^ b^c = a^ (b*c)
(4^-3)(x^-3) y^(-6*-3)
(4^-3)(x^-3) y^(18)
If we do not want negative exponents
a ^ -b = 1/ a^b
y^18/( 4^3 x^3)
y^18/ (64 x^3)

Answer:
6 hours
Step-by-step explanation:
total: 540 mi
drove motorcycle: 40mph
drove car: 60 mph
11 hours
equation for miles: 540=40x+60y
equation for time: 11=x+y
11=x+y
-x -x
y=-x+11 <---- plug in
540=40x+60(-x+11)
540=40x-60x+660
-660 -660
-120=-20x
/-20 /-20
x=6
6 hours
