Write the following numbers in scientific notation. (a) 291.7 (b) 0.0960

Question

Taking an open book exam 

Answer 1

move the original decimal place so that the number changes to become in the range from 1.0 up to9.99999.

THEN apply 10ⁿ as the power of ten which would 'correct' (or restore) the decimal point to its original position, where n = a positive number if you moved the decimal place to the LEFT (making original version smaller), or n negative if you moved the decimal place to the RIGHT.

 

Examples   55.7 = 5.57x10¹  and 0.0062 = 6.2x10^-3
