Give the calculation of following : (i) (6.7xx10^(4))xx(8.4xx10^(7))(

1.	Give the calculation of following : (i) (6.7xx10^(4))xx(8.4xx10^(7))(ii) ((3.4xx10^(-3)))/((6.5xx10^(-7)))
Answer» Solution :(i) `(6.7xx10^(4))XX(8.4xx10^(7))=(6.7xx8.4)(10^(4+7))` `=56.28xx10^(11)` `=5.628xx10^(12)` (ii) `((3.4xx10^(-3)))/((6.5xx10^(-7)))=(3.4 div 6.5) (10^(-3+7))` `=0.5230xx10^(4)` `=5.230xx10^(5)`
