A. 2.34 × 108

B. 0.234 × 109

C. 2.34 × 10–8

D. 0.234×10–9

Answer :

Standard form is a form of writing very large or very small numbers without negative exponent and in a précised form, with decimal after one digit.


We know that,


234000000 = 234 × 1000000


234000000 = 2.34 × 100 × 106


234000000 = 2.34 × 102 × 106


By laws of exponent,


xm × xn = xm + n


234000000 = 2.34 × 102 + 6


234000000 = 2.34 × 108


Hence, the standard form for 234000000 is 2.34 × 108.
