(x^a)(x^b)=x^(a+b)
(ab)(cd)=(a)(b)(c)(d)
x^-m=1/(x^m)
(3y^-4)(2y^-4)=
(3)(y^-4)(2)(y^-4)=
(6)(y^-8)=
6/(y^8)
It would be: 11 * 90/100
= 11 * 0.90 = 9.9
So, your final answer is 9.9
Hope this helps!
0.9 = -4.7 - 0.6z
0.9 + 4.7 = -0.6z
5.6 = -0.6z
z = 5.6 ÷ -0.6
z = -9.33
Answer:3 & 4
Step-by-step explanation: those are the two with multiplication/division
