Answer:
x^9
----------------
125 y^12
Step-by-step explanation:
(5x^-3 y^4)^-3
We know that (ab)^c can be split into a^ * b^c
5^-3 *x^-3 ^-3* y^4 ^-3
We also know that a^b^c = a^ (b*c)
5^-3 *x^(-3 *-3) * y^(4 *-3)
5^-3 *x^(9) * y^(-12)
We know that negative exponents in the numerator move it to the denominator. The exponent stays the same except for the negative.
1/5^3 * x^9 * 1/ y^12
We know that 5^3 = 125
Rearranging the order
x^9
----------------
125 y^12
Assuming the equation would be
10 - x/5 = -4
you can solve for x
multiply both sides
50 - x = -20
move 50 to the other side
-x = -20-50
-x=-70
or x=70
$0.20 Because since one ribbon for one foot equals $0.10 (10 cents), you have two feet so you would have to multiply or add $0.10 and $0.10 by multiplying, you would have to multiply 10 two times which would give you 20. To add you would add 10 plus 10 and you would get yet again 30. After that you just put the form as cents which would be $0.20 :)
