1. : 1. 47 0.68 : 1. 0.404762 : 0. 595238
Answer:

Step-by-step explanation:
In order to find which expression is equivalent to
, we need to note the order of operations.
PEMDAS tells us that when solving an equation, we'd go in this order.
<em>P</em><em>arentheses</em>
<em>E</em><em>xponents</em>
<em>M</em><em>ultiplication/</em><em>D</em><em>ivision</em>
<em>A</em><em>ddition/</em><em>S</em><em>ubtraction</em>
Using this, we'd start by evaluating what's inside the parentheses,
. We'd then bring that value to the 0th power.
<em>Wait...</em> there's something special about bringing anything to the 0th power. Bringing anything to the 0th power makes the value 1.
It can be -5... it can be 1,000,000, any number possible, taken to the 0th power, will always be 1.
So no matter what the value inside the parentheses is, taking it to the 0th power will <u>always make it 1</u>.
Therefore, this expression is equivalent to 1.

We are given the expression,
54x+81
Here we have to find Greatest Common Factor of 54 and 81
Factors of 54 are 1, 2, 3, 6, 9, 18 and 27.
Factors of 81 are 1, 3, 9, 27 and 81.
Greatest common factor of 54 and 81 is 27.
So we take out 27 common, rewriting the expression
27(2x+3)
Answer: 54x+81 in factored form equals 27(2x+3).
