To convert the expanded form into exponent form or what is commonly known as scientific notation, you have to move the decimal place until you reach the last digit. From its original place, there are 6 places in order to reach to the last digit. Since you moved to the right, the exponent would have a positive sign. The scientific notation would be 6*10⁶ m.
