Final answer:
The expression 2.4 x 10^-4 in scientific notation simplifies to 0.00024 by moving the decimal point four places to the left. This is part of larger mathematical concepts involving scientific notation and the manipulation of numbers expressed as a power of ten.
Step-by-step explanation:
The question revolves around the concept of scientific notation and simplifying expressions. To simplify an expression like 2.4 x 10-4, we are dealing with a number that is expressible as a power of ten. This specific notation indicates that the decimal point in the number 2.4 is moved four places to the left because of the negative exponent, resulting in 0.00024. When working with scientific notation, moving the decimal place to the right for a positive exponent or to the left for a negative exponent is the key operation.
For the provided values, we see varying powers of ten which represent different magnitudes of numbers. These numbers can be used to perform calculations, compare values, or express very large or small numbers in a more manageable form.
