Basically when you use parantheses it protects that number from becoming negative...
-10^2 is -100 but with paranthesis is 100
1.
2. and
3.
Example:
Step-by-step explanation:
1. We have , and we have to prove that this term is equivalent to .
Now,
=
{Since we know the property of exponent as }
3. The power of products property gives
........ (1)
For example, we can write,
The answer is in the image
Cost of 7 gallons=$24.50
Cost of 1 gallon=24.50/7=3.5
Cost of 15 gallons=15*3.5=52.5
Cost of 15 gallons will be $52.5
For 1 flavor there are 9 topping
Therefore, for 5 different flavors there will be 5*9 choices
No of choices= 5*9
=45
The solution is given in the image below
It will provide an instant answer!
