0.25= 1/n

Solution

0.25 = \frac{1}{n}

n = 4

Solution steps

0.25 = \frac{1}{n}

Multiply both sides by

n

0.25 n = 1

Divide both sides by

0.25

n = 4

Verify Solutions

Find undefined (singularity) points:

n = 0

Combine undefined points with solutions:

n = 4

\frac{e ^{- 4}}{t} = \frac{1}{4}

\frac{( 5 + x )}{( 5 - x )} - \frac{( 5 - x )}{( 5 + x )} = \frac{33}{4}

0.1 t^{2} = \frac{200}{t}

\frac{3}{4 ( x - 6 ) ^{2} + 1} = 28

\frac{∣ - 0.42 ∣}{∣ x ∣} = ∣ 0.7 ∣
