Answer 1

Answer:

${ (\frac{1}{3}) }^{ - 1} - {(\frac{1}{4})}^{ - 1} \\ \\ = \frac{1}{ \frac{1}{3} } - \frac{1}{ \frac{1}{4} } \\ \\ = 3 - 4 \\ = - 1$

So, -1 is the correct answer

Answer 2

A positive exponent tells us how many times to multiply a base number, and a negative exponent tells us how many times to divide a base number. ... We can rewrite negative exponents like x⁻ⁿ as 1 / xⁿ. For example, 2⁻⁴ = 1 / (2⁴) = 1/16.
