The equivalent expression 
Step-by-step explanation:
Given:
We need to find the equivalent for given expression.
Solution:
Now by using Law of indices which states;
So applying the same in given expression we get;
Now we can say that;
Also
Now We know that;
On substituting we get;
Hence The equivalent expression
Answer:
b = 1
Step-by-step explanation:
8 = b - 1 + 8b
<em>combine like terms</em>
8 = 9b - 1
<em>add 1 to both sides of the equation</em>
<em>8 + 1 = 9b - 1 + 1</em>
<em>8 + 1 = 9b</em>
9 = 9b
<em>divide both sides of the equation by 9</em>
9/9 = 9b/9
1 = b

Unit price would be the price per ounce.
Divide the total cost by the number of ounces:
Price Club : 2.59 / 12 = $0.216 per ounce
Shop Mart: 1-1/2 pounds = 1.5 x 16 = 24 ounces.
4.68 / 24 = $0.195 per ounce.
To solve both of these expressions, we want to add or subtract from left to right.
For the first one, we can rewrite it as:
8-6-9
=2-9
=-7
The second one we can rewrite as:
5-7+9+8-4
=-2+9+8-4
=7+8-4
=15-4
=11
