simplify (3.9-4)/(3.9^2-5(3.9)+4)

simplify

\frac{3.9 - 4}{3. 9 ^{2} - 5 ( 3.9 ) + 4}

0.34482 \dots

Solution steps

\frac{3.9 - 4}{3. 9 ^{2} - 5 ( 3.9 ) + 4}

Remove parentheses:

(a) = a

= \frac{3.9 - 4}{3. 9 ^{2} - 5 \cdot 3.9 + 4}

Subtract the numbers:

3.9 - 4 = - 0.1

= \frac{- 0.1}{3. 9 ^{2} - 5 \cdot 3.9 + 4}

3. 9^{2} - 5 \cdot 3.9 + 4 = - 0.29

= \frac{- 0.1}{- 0.29}

Apply the fraction rule:

\frac{- a}{- b} = \frac{a}{b}

= \frac{0.1}{0.29}

Divide the numbers:

\frac{0.1}{0.29} = 0.34482 \dots

= 0.34482 \dots

3 y + 3 y + 5 + 7 x^{3} - y - 6 - 7 x^{3}

\frac{e ^{0}}{( 1 + e ^{0} ) ^{2}}

(\frac{- 2}{3})^{4}
