Use Negative Exponents Where Necessary to Write the Expression with All

question 10

Multiple Choice

Use negative exponents where necessary to write the expression with all variables in the numerator of a term. That is,
write each term in the form c $c x ^ { n }$ if the term contains a variable.
- $$y = 6 x - 4 + \frac { 8 } { x ^ { 4 } } - \frac { 1 } { \sqrt { x } } + \frac { 1 } { \sqrt [ 3 ] { x ^ { 2 } } }$$

• A) \(y = 6 x - 4 + 8 x ^ { - 4 } - x ^ { - 2 } + 1 x ^ { - 3 / 2 }\)
• B) \(y = 6 x - 12 + x ^ { - 4 } - x ^ { - 1 / 2 } + x ^ { - 2 / 3 }\)
• C) \(y = 6 x - 4 + ( 8 x ) ^ { - 4 } - x ^ { - 1 / 2 } + ( 1 x ) ^ { - 2 / 3 }\)
• D) \(y = 6 x - 4 + 8 x ^ { - 4 } - x ^ { - 1 / 2 } + 1 x ^ { - 2 / 3 }\)
