Is 6.49999 x 10^7 = 5? to one significant figure sorry

OpenStudy (skullpatrol):

No.

OpenStudy (anonymous):

It's just 6 to one significant figure

OpenStudy (anonymous):

64*

OpenStudy (anonymous):

Oh dang I put the wrong thing LOL, sorry I mean does it go to 7, but obviously not. I thought the 9 might raise the 4 to a 5 and thus the 6 then becomes a 7.

OpenStudy (skullpatrol):

$$\ 6.49999 * 10^7 =64,999,900$$

OpenStudy (anonymous):

Rounded to one significant figure

OpenStudy (skullpatrol):

$$\huge\text{60,000,000}$$

Thankyou

OpenStudy (skullpatrol):

Rounding only works on ONE decimal place, you can NOT have a chain of rounding...

OpenStudy (anonymous):

Thanks so much for that :)

OpenStudy (skullpatrol):

With the one exception that 0.999...= 1

OpenStudy (anonymous):

Ok :)

OpenStudy (skullpatrol):

For your question it would be 6.49999... x 10^7 = 64,999,999.999... = 65,000,000
