Write the following in standard form: (i) 0.000000456 and (ii) 34500000.

We have

(i) 0.000000456 = $space 456 over 1000000000$

 = $space fraction numerator 4.56 over denominator 1000000000 end fraction space cross times space 100$

 $space space equals fraction numerator 4.56 over denominator 10 to the power of 7 end fraction$
