The scientific notation for the value  [tex]\frac{9 \times 10^9}{4.5 \times 10^1}[/tex] is  2  [tex]\times[/tex]  10 ^8 .

Explanation:  

  • Scientific notation is a method for communicating numbers that are too enormous or too little to even think about being easily written in a decimal structure.  
  • To compose a number in scientific notation:  
  • Put the decimal after the main digit and drop the zeroes.
  • Now  calculating the values in scientific notation using the following formula,

                            a ^x  / a^ y  =  a ^(x  −  y )

                                            = 9  ×  10 ^9  / 4.5  ×  10 ^1

                                            =  9  / 4.5  ×  10 ^(9 − 1)

                                            = 2  [tex]\times[/tex]  10 ^8

     The scientific notation for the value  [tex]\frac{9 \times 10^9}{4.5 \times 10^1}[/tex]  is 2  [tex]\times[/tex]  10 ^8 .
