express 380 in a standard form?
3.8 x 10^2 in standard form
To express 380 in standard form, we need to write it in scientific notation. Standard form represents a number as a decimal multiplied by a power of 10.
To convert 380 to scientific notation, we first need to determine the number of digits before the decimal point. Since 380 has three digits, we can write it as 3.80 × 10² in scientific notation.
Therefore, the standard form of 380 is 3.80 × 10².
To express a number in standard form, we usually write it in scientific notation. In scientific notation, a number is expressed as a product of a decimal number between 1 and 10 and a power of 10.
To express 380 in standard form, we can follow these steps:
1. Determine the decimal number: Find a number between 1 and 10 that, when multiplied by a power of 10, gives us 380. In this case, we can use 3.8.
2. Determine the power of 10: Determine how many times 10 needs to be multiplied by itself to equal the original number. In this case, we need to multiply 10 by itself twice (10 × 10 = 100) to get 380. So, the power of 10 is 2.
3. Write in scientific notation: Now, we can express 380 in standard form by writing it as 3.8 × 10^2.
Therefore, 380 in standard form is 3.8 × 10^2.
