simplify (7.9-8)/(7.9^2-9(7.9)+8)

simplify

\frac{7.9 - 8}{7. 9 ^{2} - 9 ( 7.9 ) + 8}

0.14492 \dots

Solution steps

\frac{7.9 - 8}{7. 9 ^{2} - 9 ( 7.9 ) + 8}

Remove parentheses:

(a) = a

= \frac{7.9 - 8}{7. 9 ^{2} - 9 \cdot 7.9 + 8}

Subtract the numbers:

7.9 - 8 = - 0.1

= \frac{- 0.1}{7. 9 ^{2} - 9 \cdot 7.9 + 8}

7. 9^{2} - 9 \cdot 7.9 + 8 = - 0.69

= \frac{- 0.1}{- 0.69}

Apply the fraction rule:

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

= \frac{0.1}{0.69}

Divide the numbers:

\frac{0.1}{0.69} = 0.14492 \dots

= 0.14492 \dots

s (s + 1) (s + 3) (s + 4)

(2 a^{4} - y^{5})^{3}

\frac{2}{3 2}

(0.5 x + 2 y)^{2}

\frac{2}{5} + (- \frac{6}{35})
