Question

Evaluate the following expression: 5z + 3n - z^3 n = 7 z = 1

Answer 1

Answer:

25

Step-by-step explanation:

So first we'll input the numbers then since we have them.

5(1) + 3(7) - 1^3

So we're going to use the order of operations here first (PEMDAS) and start with the exponent because the parenthesis I used just represent multiplication. And 1 to the power of anything is still 1. Even 1^1000000000000000000000000000.....

It's still 1.

So now we have this:

5(1) + 3(7) - 1

Now we can multiply:

5 + 21 - 1

Then, add and subtract:

26 - 1

To get:

25
