# How do you express 1/39 as an expression using a negative exponent other than -1? (i.e. Not 39^-1)

${6.245}^{-} 2 \left(3 \mathrm{dp}\right)$

#### Explanation:

$\frac{1}{39} = \frac{1}{\sqrt{39}} ^ 2 = {\left(\sqrt{39}\right)}^{-} 2 = {6.245}^{-} 2 \left(3 \mathrm{dp}\right)$[Ans]

$2 \times {78}^{-} 1$

#### Explanation:

The only way I can see this is to create an equivalent fraction and write with negative exponent. That is.

$\frac{1}{39} \times \frac{2}{2} = \frac{2}{78} = 2 \times {78}^{-} 1$

$\text{or } \frac{1}{39} = \frac{1}{3 \times 13} = \frac{1}{3} \times {13}^{-} 1$

If this is not what is required you can get back to me.
