Sam is comparing the half life of two isotopes of uranium the half-life of uranium minus -238 is 4.5 * 10 9 years the half life of uranium minus 233 is 1.6 * 10 5 years he computed how much greater the half life of uranium minus 238 is than that of uranium minus 233 and his calculator displayed the number 2.81E4 what is this number in scientific notation Oxford sunrise
The number 2.81E4 in scientific notation is 2.81 x 10^4.
To convert the number 2.81E4 to scientific notation, you can rewrite it as follows:
2.81E4 = 2.81 × 10^4
Therefore, the number 2.81E4 in scientific notation is 2.81 × 10^4.
To understand the number "2.81E4" in scientific notation, let's break it down step by step.
Scientific notation is a way of writing numbers using powers of 10. It consists of two parts: a coefficient and an exponent. The coefficient is a number between 1 and 10, and the exponent represents the power of 10.
In the given number "2.81E4", the coefficient is "2.81" and the exponent is "4". To convert this to regular notation, we need to multiply the coefficient by 10 raised to the power of the exponent.
2.81E4 = 2.81 × 10^4
To further simplify, we can calculate the value of 10^4:
10^4 = 10,000
Therefore, the number "2.81E4" in scientific notation is equal to 2.81 × 10,000, which is 28,100.
