Calculate 0.25 * 10 deg - 4.73 * 10 ^ 6 Express your answer in scientific notation to 2 decimal places.
To calculate this expression, we first need to evaluate each term separately.
0.25 * 10 deg = 0.25 * 10^1 = 2.5
Next, we will evaluate the second term:
4.73 * 10 ^ 6 = 4.73 * 10^6
Now, we can subtract the two values:
2.5 - 4.73 * 10^6 = -4.72 * 10^6
Finally, we express the result in scientific notation to 2 decimal places:
-4.72 * 10^6.
To calculate the expression, we will start by performing the multiplication:
0.25 * 10 = 2.5
Next, we need to calculate the exponent:
10^6 = 10,000,000
Now, we can substitute these values back into the expression:
2.5 - 4.73 * 10,000,000
Finally, we can simplify the expression:
2.5 - 47,300,000
Expressing this in scientific notation, we get:
-4.71 * 10^7
So, the answer in scientific notation to 2 decimal places is -4.71 * 10^7.
To calculate the expression, we need to follow the order of operations (PEMDAS) and apply the rules for working with scientific notation.
Step 1: Multiply the decimal numbers separately and subtract the results:
0.25 * 10^0 - 4.73 * 10^6
Step 2: Convert the result to scientific notation. Scientific notation is expressed as a number between 1 and 10 (the coefficient) multiplied by a power of 10 (the exponent).
For the first term, 0.25 * 10^0 = 0.25 * 1 = 0.25
For the second term, 4.73 * 10^6 is already in scientific notation.
Step 3: Subtract the results from step 2:
0.25 - 4.73 * 10^6 = -4.72999975 * 10^6
Step 4: Round the result to two decimal places, keeping in mind that we need to round the coefficient and not the exponent:
-4.73 * 10^6
Therefore, the result is approximately -4.73 * 10^6 in scientific notation to 2 decimal places.
