each second, a star converts 4.0×10⁷ tons of hydrogen into helium and energy in the form of gamma rays. write this number in standard notation.\n4.0×10⁷ =
Answer
Explanation:
Step1: Recall scientific - notation rule
In scientific notation (a\times10^{n}), when (n>0), move the decimal point (n) places to the right.
Step2: Move the decimal point
For (4.0\times 10^{7}), since (n = 7), move the decimal point 7 places to the right. We get (40000000).
Answer:
(40000000)
