Question: How do you solve [3.2 x (6.1 x 6.3)] - 2.8 with PEMDAS?
PEMDAS is the order of operations with which you solve an equation. So first parentheses, then exponents, then multiplication, then division, then addition, and last subtraction.

Answer: First, you solve the parentheses in the parentheses:
>6.1 x  6.3 = 38.43
Now ur equation is: (3.2 x 38.43) - 2.8
Now you solve what's inside this parentheses:
>3.2 x 38.43 = 122.976
Now you do the subtraction, because you have already solved all of what's in the parentheses:
>122.976 - 2.8 = 120. 176
And so, your answer is 120.176
This is what your equation should look like when you're solving:
>[3.2 x (6.1 x 6.3)] - 2.8 = y
>[3.2 x (38.43)] - 2.8 = y
>(3.2 x 38.43) - 2.8 = y
>122.976 - 2.8 = y
>122.976 - 2.8 = 120. 176

6.1×6.3=38.43
(3.2×38.43)- 2.8
3.2×38.43=122.976
That leaves you with 122.976-2.8
122.976-2.8=120.176

Answer:

  30500 = 3.05·10^4

Step-by-step explanation:

Your calculator can do this for you. You may need to set the display to scientific notation, if that's the form of the answer you want.

__

This can be computed by converting both numbers to standard form:

  (5·10^2) +(3·10^4)

  = 500 +30000 = 30500 = 3.05·10^4

__

Addition of numbers in scientific notation in general requires that they have the same power of 10. It may be convenient to convert both numbers to the highest power of 10.

  5·10^2 + 3·10^4

  = 0.05·10^4 +3·10^4 . . . . now both have multipliers of 10^4

  = (0.05 +3)·10^4

  = 3.05·10^4
