Questioname the Field Axiom that was use x+(y+z)=(x+y)+zx+(y+z)=(x+y)+z

Studdy Solution

STEP 1

What is this asking? Which of the field axioms is shown by the equation x+(y+z)=(x+y)+zx + (y + z) = (x + y) + z? Watch out! Don't confuse the **associative property of addition** with the **commutative property of addition** (x+y=y+xx + y = y + x) or the **distributive property** (a(b+c)=ab+aca \cdot (b + c) = a \cdot b + a \cdot c).

STEP 2

1. Recall the field axioms.
2. Identify the relevant axiom.

STEP 3

Let's **refresh** our memory on the field axioms!
Remember, field axioms are **fundamental rules** that govern how numbers in a field behave under addition and multiplication.
They're like the **basic building blocks** of arithmetic!

STEP 4

There are quite a few axioms, including **associativity**, **commutativity**, **identity elements**, **inverses**, and the **distributive property**.
We're looking for the one that matches the given equation.

STEP 5

The given equation, x+(y+z)=(x+y)+zx + (y + z) = (x + y) + z, shows that it doesn't matter how we **group** numbers when we add them.
Adding xx to the sum of yy and zz gives the same result as adding the sum of xx and yy to zz.

STEP 6

This is precisely the **definition** of the associative property of addition!
It tells us that we can **rearrange the parentheses** in an addition problem without changing the outcome.

STEP 7

The field axiom demonstrated by the equation x+(y+z)=(x+y)+zx + (y + z) = (x + y) + z is the **associative property of addition**.
