Answer :
To solve the problem, follow these steps:
1. First, compute the value of the exponent:
[tex]$$10^2 = 10 \times 10 = 100.$$[/tex]
2. Multiply [tex]$8.4$[/tex] by [tex]$100$[/tex]:
[tex]$$8.4 \times 100 = 840.$$[/tex]
Thus, the number [tex]$8.4 \times 10^2$[/tex] is equal to [tex]$840$[/tex], which corresponds to option C.
