heres how i got that answer

first step

any expression raised to the power of 1 equals its self. remove unnecessary parentheses

(6.83 x 10) - 9.1 x 10^-1

second step

6.83 x 10 = 68.3 then make the other decimal into a fraction so 91 over 10 or 91/10 any expression raised to the power of - 1 equals its reciprocal so now you have

68.3 - 91/10 x 1/10

third step

convert the decimal into a fraction 683/10

then multiple 91/10 and 1/10 to get 91/100

so now you should have 683/10 - 91/100

last step

subtract the fractions giving you

6739 over 100
