Q11: Is the number written in scientific notation? If not explain why not.
950 x 10^5
Q12: Find the simplified form of the expression. Give your answer in scientific notation.
(6x10^4) (4.8x10^2)
Q13: Write the number in scientific notation
79,500,000,000
Q11: No, the number 950 x 10^5 is not written in scientific notation. Scientific notation is written in the form of a number between 1 and 10 multiplied by a power of 10. In this case, the number is already multiplied by 10^5, so it is not in scientific notation.
Q12: To find the simplified form of (6x10^4) (4.8x10^2) in scientific notation, we can multiply the numbers and combine the powers of 10.
(6x10^4) (4.8x10^2) = 6 * 4.8 * 10^4 * 10^2
= 28.8 * 10^(4+2)
= 28.8 * 10^(6)
= 2.88 x 10^(7)
Therefore, the simplified form of (6x10^4) (4.8x10^2) in scientific notation is 2.88 x 10^7.
Q13: To write the number 79,500,000,000 in scientific notation, we need to move the decimal point to the left until only one digit is left to the left of the decimal point.
79,500,000,000 = 7.95 x 10^10
Therefore, the number 79,500,000,000 in scientific notation is 7.95 x 10^10.
