Evaluate

-\frac{3}{10}=-0.3

$−103 =−0.3$

Solution Steps

5 ^ { - 1 } - \frac { 1 } { 2 }

$5_{−1}−21 $

Calculate 5 to the power of -1 and get \frac{1}{5}=0.2.

Calculate $5$ to the power of $−1$ and get $51 =0.2$.

\frac{1}{5}-\frac{1}{2}\approx -0.3

$51 −21 ≈−0.3$

Subtract \frac{1}{2}=0.5 from \frac{1}{5}=0.2 to get -\frac{3}{10}=-0.3.

Subtract $21 =0.5$ from $51 =0.2$ to get $−103 =−0.3$.

-\frac{3}{10}=-0.3

$−103 =−0.3$
