Physics lecture 06 Topic S.F example

2.50 exponent 2 

Sir yeh example wrong he q k sir jb hum ise Scientific form se Standard Form m convert krte hn to 2 S.F ate hn lekin apne Scientific form mn 3 S.F likha he iska shi version yeh hoga 2.5 exponent 2

@Sir Bilal

Yeah! you are right, i also noticed it, Sir has done a Mistake here....

DEAR JUNAID ..  2.50exponent2 hi asal standard exponent form me hy .. is me 3 S.F hy or agar hm zero remove remove krdy gy to 2 S.F reh jaaye gy .. is ka mtlb is ki accuracy km ho jaaye gi or S.F humy accuracy hi ko show krta hy.. hope u get it

Mr. Shehroz, if you convert 2.50 ex ^ 2 to standard form then there will be 2 S.F and it is necessary that both standard and scientific form contain same number of significant figure, so the correct exponential form must be 2.5 ex ^ 2
