What is 2.3 x 107 in decimal notation?
2.3*107 is 23000000.
What are the rules in subtractin in significant notation?
First ensure that the exponents (the powers of the multipliers of the tens) are the same - if necessary adjust the smaller number by shifting the decimal point left until the powers are the same; for example if the exponents are ``x 105'' and ``x 103'' shift the decimal point of the second number 5 - 3 = 2 places to the left and then the numbers will have the same exponents. Now, align the decimal points and subtract the mantissae (the numbers before the ``x 10'' s) as usual. Finally, adjust the result to correct into standard form if necessary by shifting the decimal point. Examples: 2.3 x 107 - 2.275 x 106 = 2.3 x 107 - 0.2275 x 107 = (2.3 - 0.2275) x 107 = 2.0725 x 107 2.3 x 107 - 2.275 x 107 = (2.3 - 2.275) x 107 = 0.025 x 107 = 2.5 x 105
What is the scientific notation for 0.000468 meters?
0.000468 meters in Scientific Notation = 4.68 x 10-4 meters.Move 4 decimal places to the right to obtain negative exponent for base 10. Therefore, the number in scientific notation is 4.68 x 10-4 meters.
What is 7.5 meters x 4 meters in square meters?
7.5 x 4 = 30 square meters
What is the number 6.17 x 107?
6.17 x 107 = 660.196.17 multipled by 10 to the power of 7, which you may have meant is 61700000. We just move the decimal point 7 places to the right.
