Q. How do you write 5.8×105 in standard form?_____
Move Decimal Point: To write the number 5.8×105 in standard form, we need to move the decimal point in 5.8 five places to the right, because the exponent on 10 is 5.
Multiply by Powers of 10: Moving the decimal point five places to the right gives us 580000. This is because each power of 10 multiplies the number by 10, so 5.8 becomes 58, then 580, then 5800, then 58000, and finally 580000.
