Answer:
-4
Step-by-step explanation:
What I did was multiply 9/1 with 2/3 giving us 18/3 which simplifies into 6. Then what we do is subtract 2 with 6 giving us -4.
.8 it represents .80 cents. rather than .08 which would represent 8 pennies
17 1/8 i’m really pretty sure
The exact answer is 12 root 2, but you can also say approximately 17.
I got this by finding the square root of 369, and then 81. After finding these values, you get the equation...
a^2 + 9^2 = 369
a^2 + 81 = 369
a^2 = 288
And then I just found the square root of 288
When you have an exponent divided by another exponent, you subtract the exponents (only when it has the same base)
For example:

When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive
For example:



1. 
2. 
3. 
4. 
5. 
This is one of the ways you could have done it
6. 
7.
Divide 63 and 9

If you multiply an exponent directly with another exponent, you multiply the exponents together
For example:


If you multiply a variable with an exponent by a variable with an exponent, you add the exponents
For example:
