Q. Write the answer in proper scientific notation:500x1041
Express in Scientific Notation: First, we need to express 500 in scientific notation.500 can be written as 5×102 because 5 times 10 squared equals 500.
Rewrite with Scientific Notation: Now, we rewrite the original expression using the scientific notation for 500. The expression becomes (1)/(5×102×104).
Combine Powers of 10: Next, we combine the powers of 10 using the rule of exponents that states when you multiply powers of 10, you add the exponents.So, 102×104 becomes 10(2+4), which is 106.
Adjust Coefficient: The expression is now (1)/(5×106). To write this in scientific notation, we need to have a number between 1 and 10 multiplied by a power of 10. Since 5 is already between 1 and 10, we can write the expression as 1×10−6 divided by 5.
Divide in Scientific Notation: To divide by 5 in scientific notation, we can adjust the coefficient from 1 to 1/5. 1/5 is 0.2, so the expression in scientific notation is 0.2×10−6.
Check Proper Notation: Finally, we check if 0.2×10−6 is in proper scientific notation. Since 0.2 is between 1 and 10, and the power of 10 is written as an exponent, the expression is in proper scientific notation.
