Is the number written in scientific notation? If not, explain.
a. 0.15 x 10 4
b. 7.06 x 10−8
c. 3.3 x 100 12
To determine whether a number is written in scientific notation, we need to check if it is in the form of "a x 10^b" where "a" is a decimal number between 1 and 10, and "b" is an integer.
a. 0.15 x 10^4: This number is written in scientific notation since it follows the required form. "a" in this case is 0.15 (a decimal number between 1 and 10), and "b" is 4 (an integer).
b. 7.06 x 10^-8: This number is written in scientific notation because it follows the required form. "a" in this case is 7.06 (a decimal number between 1 and 10), and "b" is -8 (an integer).
c. 3.3 x 100^12: This number is NOT written in scientific notation because it does not follow the required form. The exponent should be applied to the 10, not the 100 in this case. A correct representation in scientific notation would be 3.3 x 10^12.
In summary, options a and b are written in scientific notation, while option c is not.
