-10y^2 + (-3y^2) - 4y^2 - (-6y^2) =
-10y^2 - 3y^2 - 4y^2 + 6y^2 =
-17y^2 + 6y^2 =
- 11y^2
The answer is 144.5 cm squared
Step 1
To find a, take the number and move a decimal place to the right one position. Original Number: 58,927
New Number: 5.8927
Step 2
Now, to find b, count how many places to the right of the decimal. New Number: 5 . 8 9 2 7
Decimal Count: 1 2 3 4
There are 4 places to the right of the decimal place. Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation. Remember, the notation is: a x 10b a = 5.8927 b = 4 Now the whole thing: 5.8927 x 104 Step 4
Check your work: 104 = 10,000 x 5.8927 = 58,927
