0.686 = 686/1000 = 343/500
it would be 7 raised to the third power for exponential form and 7x7x7in expanded form and 343 in standard form .
73 = 343
73 7*7*7 = 343
3.43 = 343/100
Well, honey, to write 7x7x7x7 in standard form, you just gotta multiply those 7's together. 7x7 is 49, and 49x7 is 343, and finally, 343x7 is 2401. So, in standard form, 7x7x7x7 is simply 2401. Hope that clears things up for ya!
