Which expression is equivalent to 0.000000034
A 3.4 x 10^ -7
B 3.4 x 10^8
C 3.4 x 10^ -8
D 3.4 x 10^7
The decimal has moved so that it lies between 3 and 4, that is 3.4
count the number of places it has moved and remember that a scientific number with a positive exponent on 10 is "large" and one with a negative exponent on 10 is "small"
Let me know what conclusion you reach.
To determine which expression is equivalent to 0.000000034, we need to understand scientific notation.
Scientific notation is a way to write very large or very small numbers in a concise and standardized format. It consists of two parts: a coefficient and an exponent of 10. The coefficient is usually a number between 1 and 10, and the exponent represents the power of 10 by which the coefficient is multiplied.
In this case, the given number is 0.000000034. To convert it to scientific notation, we can start by moving the decimal point to the right until there is only one non-zero digit to the left of the decimal point. In this case, we move the decimal point 7 places to the right, resulting in 3.4.
Next, we count the number of places we moved the decimal point to determine the exponent. Since we moved it 7 places to the right, the exponent is -7.
Combining the coefficient (3.4) and the exponent (-7), we can express the number 0.000000034 in scientific notation as:
3.4 x 10^-7
Therefore, option A, 3.4 x 10^-7, is the expression that is equivalent to 0.000000034.
