c) (36x) / (-6y)=

d) x – [3x + 2(– x + 1)] =

e) 6x · 6y =

f) 4 2 / 3 -2 =

g) y 2 / y 5 =

h) [(ab) 3] 2 =
 

Answer 1

3(45)=
135 ✔✔


3a(2b)=
6ab ✔✔


(36x)÷(-6y)=
-6x/y ✔✔


x-[3x+2(-x+1)]=
x-[3x-2x+2]=
x-3x+2x-2=
0-2=
-2 ✔✔


(6x)(6y)=
36xy ✔✔


42÷3-2=
42÷1=
42 ✔✔


y²÷y^5=
1/y³ ✔✔


[(ab)³]²=
[a³b³]²=
a^6•b^6 ✔✔
