Solve (1){(e)^-frac{-1^2{2}}}

$$(1) {(e)^{ - \frac{ - { 1 }^{ 2 } }{ 2 } }}$$

Evaluate

$$\sqrt{e}\approx 1.648721271$$

Solution Steps

Calculate 1 to the power of 2 and get 1.

$$1e^{-\frac{-1}{2}}$$

Fraction \frac{-1}{2} can be rewritten as -\frac{1}{2} by extracting the negative sign.

$$1e^{-\left(-\frac{1}{2}\right)}$$

The opposite of -\frac{1}{2} is \frac{1}{2}.

$$1e^{\frac{1}{2}}$$

For any term t, t\times 1=t and 1t=t.

$$e^{\frac{1}{2}}$$
