4=c
c=4
Answer:
c = 4
8= 2c
c = 8/2
hope this helps you!
(3/4)^4 = 81/256
1 ÷ 81/256 = 256/81

commutative property of addition : x + y = y + x
example : 2+3 =5 and 3+2 =5 then 2+3=3+2
associative property of addition
x + y + z = (x + y) + z = x + (y + z)
example: 2+3+4 = (2+3)+4 = 5 + 4 =9
2+3+4 = 2+(3+4) = 2 + 7 = 9
