Following PEMDAS, it states that you should start with parenthesis first. In this case, there are none, so you find exponents. Again, there isn't any, so you move onto multiplication. And yes, there is. 
Although, keep in mind that if there is multiplication and division, you don't ALWAYS do multiplication first. If there is both multiplication and division just start from the left to the right. 
1) So, the first step to solving this problem is taking 9 x 9 which is 81.
2) The second step would be skipping over to the division and solve 9/9 which is 1. 
3) Now, your equation is 81 + 1 - 9 = 
4) The fourth step to solve this equation is follow pemdas and solve. PEMDAS states that you do addition before subtraction. Although, if there is addition and subtraction at the same equation just go from left to right. 
5) 81 + 1 - 9 = 82 - 9 = 73

The answer would then be 73.

Start from the beginning 9 x 9 is 72
72 + 9 is 81 Then 81 divide by 9 which is 9 then 9 - 9 Is 0
So the answer to that is 0 hope i helped! :)

Fundamental theorem of calculus<br> <img src="https://tex.z-dn.net/?f=g%28s%29%3D%5Cint%5Climits%5Es_6%20%7B%28t-t%5E4%29%5E6%7D

Answer:

\displaystyle g'(s) = (s-s^4)^6

Step-by-step explanation:

The Fundamental Theorem of Calculus states that:
\displaystyle \frac{d}{dx}\left[ \int_a^x f(t)\, dt  \right] = f(x)

Where <em>a</em> is some constant.

We can let:
\displaystyle g(t) = (t-t^4)^6

By substitution:

\displaystyle g(s) = \int_6^s g(t)\, dt

Taking the derivative of both sides results in:
\displaystyle g'(s) = \frac{d}{ds}\left[ \int_6^s g(t)\, dt\right]

Hence, by the Fundamental Theorem:

\displaystyle \begin{aligned} g'(s) & = g(s) \\ \\  & = (s-s^4)^6\end{aligned}

What is the volume of a box measuring 1mX5mX6m?
Flauer [41]

Hey!

To find volume, you have to multiply the length, width, and height. All you have to do is multiply the 3 numbers together.

1 \times 5 \times 6 = 30

<em>The volume is 30 m³.</em>

Good luck and hope this helps! :)
