On the way home from visiting his family, vincentβs plane cruised at an altitude of 3.2 Γ 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 Γ 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincentβs problem in standard notation. part a write the cruising altitude of vincentβs plane in standard notation.
