Answer:
see explanation
Step-by-step explanation:
(x - 4)² = 5 ( take square root of both sides )
x - 4 = ± 
( add 4 to both sides )
x = 4 ±
that is
x = 4 - , x = 4 +
Using rule 5.
Answer: g^4/h^4
I hope I helped. Look up "Exponent rules" Make a song it'll help you memorize it. Actually, it was how dad taught me when I was 13yrs old :)

The commutative property of multiplication is just the numbers switched around, but it doesn't change the product. It has to in multiplication.
Answer:
40
Step-by-step explanation:
let the unknown be y (x is used as times(multiplication) )
(y-17)x-6=-138
add /-6 to both sides
y-17x-6/-6=-138/-6
y-17=23
make y independent/add 17 to both sides
y-17+17=23+17
y=40
or in an easier way
-138/-6 =23
23+17=40
simply reversing the question to get the answer
