How do I simplify this:
(The ^ symbol means 3)
-3(12)-{5(-4)-2^
I tried it,and got-8,however when I
rechecked my work I got -64. Please help!
Please help!
where is the other } in the equation? And ^ means to the power so -2^3 would be minus 2 to the 3rd power. Please rewrite your problem so it makes sense.
-3(12)-{5(-4)-2^^^}
the ^ means 2 to the 3rd power
order of operations:
start inside { } and do powers 1st. so -2 times -2 times -2= -8
Then still inside { } next:
so
5 times -4= -20
then add the -8 = -28
So now it looksa like
-3(12)-{-28}
now multiply -3 times 12 so it looks like
-36 - {-28}
Then a double - turns -28 to + 28
so -36 +28= -8
I think this is the right answer. There are far better math helpers here than me, so maybe they will double chek me.
please help
-3(12)-{5(4)-2^^^ (to the third power)
Sorry wrote problem wrong.
-3(12)-{5(-4)-2^ ^ ^}
the ^ symbol means to the third power
can someone simplify this for me?
To simplify the expression -3(12)-{5(-4)-2^3}, we can follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
First, let's solve the exponent inside the curly brackets. 2^3 means 2 raised to the power of 3, which equals 8.
Now we can rewrite the expression as -3(12)-{5(-4)-8}.
Next, let's solve the multiplication inside the parentheses. -3 multiplied by 12 equals -36.
Our expression becomes -36 - {5(-4) - 8}.
Now let's solve the multiplication inside the inner parentheses. 5 multiplied by -4 equals -20.
Our expression becomes -36 - {-20 - 8}.
Now let's simplify the subtraction inside the inner curly brackets. -20 minus 8 is -28.
Our expression becomes -36 - {-28}.
To remove the negative sign in front of the curly brackets, we can multiply -1 by every term inside the curly brackets.
This gives us -36 + 28.
Finally, we add -36 and 28 to get the simplified answer, which is -8.
So -3(12)-{5(-4)-2^3} simplifies to -8.
