Answer:
-2.8 x 10^5 or -280,000
Step-by-step explanation:
We first have to look at:
<em>P </em>: Parenthesis
<em>E </em>: Exponents
<em>M </em>: Multiply
<em>D </em>: Divide
<em>A </em>: Add
<em>S </em>: Subtract
We have to solve the question in that order:
The first thing we do is figure out the value of the exponents from left to right since there are exponents inside the parenthesis.
10^4 is just 10x10x10x10 = 10,000
10^5 same thing 10x10x10x10x10 = 100,000
Now that we know the value of the exponents we can solve the equations inside the parenthesis:
12 x 10,000 = 120,000
(120,000) - ( 4 x 100,000)
4 x 100,000 = 400,000
So the final expression is:
<u>(120,000) - (400,000) = -280,000</u>
