The correct answer is: Multiply the coefficients and add the exponents of the powers of 10.
To find the total area of tape, you need to multiply the length (1.14×10^4 mm) by the width (12.7 mm).
The product would be 1.14×10^4 mm * 12.7 mm = 1.4478×10^5 mm².
So, the correct answer is: 1.4478 times 10 superscript 5 baseline mm squared.
To find the total volume of the sugar cubes, you need to multiply the volume of one sugar cube (4.9 ml) by the number of sugar cubes (1.5×10^6).
The product would be 4.9 ml * 1.5×10^6 = 7.35×10^6 ml.
So, the correct answer is: 7.35 times 10 superscript 6 baseline ml.
To multiply 0.75 by 2.8×10^−5, you simply multiply the two numbers together.
0.75 * 2.8×10^−5 = 2.1×10^−5
So, the correct answer is: 2.1 times 10 to the negative 5 power.
A tape dispenser holds 1.14×10^4 mm of tape that is 12.7 mm wide. Multiply the two numbers to find the total area in square millimeters of tape. Write the product in scientific notation.(1 point)
