Answer:
81
Step-by-step explanation:

Using PEMDAS/BODMAS, we will have to do the exponent first, which is
.
Substitute the variable z with 6, since z = 6.

.
Thus, we will get

Solve the multiplication next.

Finally, add/subtract the numbers:


Answer:
First is direct second is non direct
Answer:
<h2>10.</h2>
Step-by-step explanation:
<u>Explanation:</u>

In order to solve this, we must use PEMDAS.
This is because there are more than one operations involved.
PEMDAS is the order in which you must solve the operations.
PEMDAS STANDS FOR:
- Parenthesis
- Exponential Notation (exponents)
- Multiplication/division (do whichever comes first)
- Addition/subtraction (do whichever comes first)
<u>Solve.</u>
Now, using PEMDAS, I will solve.
There are no parenthesis.
There are no exponents.
There is no multiplication nor division.
There is addition and subtraction.



Lastly, there is addition.

<u>Conclude:</u>
I, therefore, believe 
You did not clarify the answers of Jagan nor Mithun.
So, whichever person got the answer of 10 is correct.
