4.5 x 10^-8 = 0.000000045.
To understand what 4.5 x 10^-8 represents, we need to understand scientific notation. Scientific notation is a way of representing numbers that are either very large or very small. It consists of two parts: a coefficient and an exponent.
In this case, the coefficient is 4.5, and the exponent is -8. The coefficient can be any number between 1 and 10 (excluding 10 itself), and the exponent represents the power of 10 by which the coefficient is multiplied.
To calculate the value of 4.5 x 10^-8:
1. Write down the coefficient: 4.5
2. Move the decimal point in the coefficient to the left by the number of places indicated by the exponent:
- 8 places in this case
- 4.5 becomes 0.000000045
- Since the exponent is negative, we move the decimal point to the left (to smaller values)
- A negative exponent indicates a very small number
3. The value of 4.5 x 10^-8 is 0.000000045 or 4.5 x 10 to the power of -8
