(ii) 0.0000123 written in standard form is…..

(iii)

(iv) in usual form is…..

(v) in usual form is…..

Answer :

(i) 360000 written in standard form is 3.6 × 10^{5}

360000 = 36 × 10^{4} = 3.6 × 10 × 10^{4} = 3.6 × 10^{(1+4)} = 3.6 × 10^{5}

(ii) 0.0000123 written in standard form is 1.23 × 10^{-5}

0.0000123 =

= 1.23 × 10^{(2-7)} = 1.23 × 10^{-5}

(iii)

(iv) 3 × 10^{-3} in usual form is 0.003

3 × 10^{-3} = = 0.003

(v) 5.32 × 10^{-4} in usual form is 0.000532

5.32 × 10^{-4} = = 0.000532
