simplify (6.9-7)/(6.9^2-8(6.9)+7)

simplify

\frac{6.9 - 7}{6. 9 ^{2} - 8 ( 6.9 ) + 7}

0.16949 \dots

Solution steps

\frac{6.9 - 7}{6. 9 ^{2} - 8 ( 6.9 ) + 7}

Remove parentheses:

(a) = a

= \frac{6.9 - 7}{6. 9 ^{2} - 8 \cdot 6.9 + 7}

Subtract the numbers:

6.9 - 7 = - 0.1

= \frac{- 0.1}{6. 9 ^{2} - 8 \cdot 6.9 + 7}

6. 9^{2} - 8 \cdot 6.9 + 7 = - 0.59

= \frac{- 0.1}{- 0.59}

Apply the fraction rule:

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

= \frac{0.1}{0.59}

Divide the numbers:

\frac{0.1}{0.59} = 0.16949 \dots

= 0.16949 \dots

\frac{a ^{3} a ^{5}}{a ^{2}}

(\frac{9}{16})^{\frac{1}{2}}

\frac{2}{x ^{2}} + 3 x

1 - 81 x^{2}

41 \cdot 2
