A number is initially written in scientific notation by relocating the decimal after the first integer between 1 and 10. Your number in this instance is 0.000938. As a result, you shift your decimal four places to the right until it is behind 9, which is the first number from 1 to 10. (An additional illustration is 0.0000398. In this situation, you would shift your decimal five places so that it lies beneath the number 3.) Your new number is 9.38 since you have shifted your decimal 4 places to the right of 9. You return to your starting number to discover if your power, or , is positive or negative. Your power will be negative if the starting number is a negative one. You will have a positive power if the initial number is greater than 1. Your initial number was negative in this situation. So your power will be a negative 4 and answer is 9.38 x
