What is 1.0 x 10^9 in standard form?

The answer is:  " 1000000000 " ;  or, write as:

                       →  " 1,000,000,000 "  ;  ← {" 1 billion " .}.

Explanation:

Given the number:  " 1.0  *  10⁹ " ;  

which is given in "scientific notation" ;  

we are asked to write in "standard form" .

So, we take the:  " 1.0 " and move the decimal point :

                                    " 9 (nine) spaces to the "right" .

The reason we move the decimal point "9 (nine) spaces to the "right" ;

                           is that in scientific notation;  we are given:  

                                       "   *  10⁹ "  ;

And since the "10" is raised to the "positive 9" ;

          we move the decimal point "9 (nine) spaces to the "right" ;

{ Note:  If we were given:  "  *  10 ⁻⁹ " ;

          we move the decimal point "9 (nine) spaces to the "left" .}.

As such:

      " 1.0  *  10⁹  =  1 0 0 0 0 0 0 0 0 0 ;

         →  which is:  "the number " 1 " ;  followed by "nine (9) zeros" ;

         →  which can be written as:  " 1000000000 " ;

                       →  or ;  " 1,000,000,000 " .

                       →  { which is: " 1 billion " .}.
