# 6. 46 xx 10^5#

Explanation:

Move the decimal five places to the left to leave only one digit to the left of the decimal. Keep the three significant digit 6,4,6 . The zeros are simply place holders and are not significant. Then multiply by # 10^5# to keep the numerical value of the number the same

# 646,000 = 6.46 xx 10^5#
