How do you express in scientific notation?
The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.
How do you express 38000 in scientific notation?
The easiest way to do this is to do the following:
- write down the original number: 38000.
- place the decimal point where we put it in 3.8 : 3.8000.
- count the number of places after the decimal point (or count the number of numbers after the decimal point): 3./8/0/0/0 ← there are 4 numbers after the decimal point.
How do you express 356 in scientific notation?
Our index is positive because we need to make the number larger to get back to the original number. Therefore, 356 000 = 3.65 × 105 is expressed in scientific notation. Note that we have left off the zeros that came after the last number after the decimal point.
How do you write E in scientific notation?
The Scientific format displays a number in exponential notation, replacing part of the number with E+n, in which E (exponent) multiplies the preceding number by 10 to the nth power. For example, a 2-decimal scientific format displays 12345678901 as 1.23E+10, which is 1.23 times 10 to the 10th power.
How do you write 3.8 in scientific notation?
This time, you move the decimal point to the right, 4 spaces. N = 3.8 and x = -4. So your number in scientific notation becomes: 3.8×10-4, or 3. 8 times 10 to the negative-fourth (power.)
What is the scientific notation of 700?
7 × 102
Scientific notation
| Decimal notation | Scientific notation |
|---|---|
| 700 | 7 × 102 |
| 1,000,000 | 1 × 106 |
| 0.0004212 | 4.212 × 10-4 |
| -5,000,000,000 | -5 × 109 |
How do you write 0.096 in scientific notation?
Hence in scientific notation 0.096=9.6×10−2 (note that as we have moved decimal two points to the right, we are multiplying by 102 and hence to compensate we should divide by 102 i.e. multiply by 10−2 ).
