Reduce to simplest form. -\dfrac{7}{8}-\left(-\dfrac{5}{6}\right)=− 8 7 ​ −(− 6 5 ​ )=minus, start fraction, 7, divided by, 8, e
slavikrds [6]

Answer:

-\dfrac{1}{24}

Step-by-step explanation:

We are required to reduce the expression below to its simplest form

-\dfrac{7}{8}-\left(-\dfrac{5}{6}\right)

<u>STEP 1: </u>Remove the brackets

Take note that the product of same sign(- and -) will give you the addition sign.

-\dfrac{7}{8}-\left(-\dfrac{5}{6}\right)=-\dfrac{7}{8}+\dfrac{5}{6}

<u>STEP 2:</u> Find the Lowest Common Multiple of 8 and 6

Lowest Common Multiple of 8 and 6 is 24

<u>STEP 3:</u> Use the LCM to Simplify

-\dfrac{7}{8}+\dfrac{5}{6}=\dfrac{(-3X7)+(5X4)}{24}\\=\dfrac{-21+20}{24}\\=\dfrac{-1}{24}\\=-\dfrac{1}{24}

Therefore:

-\dfrac{7}{8}-\left(-\dfrac{5}{6}\right)=-\dfrac{1}{24}

oee [108]

Answer:

\frac{1}{81}

Step-by-step explanation:

Using the rule of exponents

a^{-m} ⇔ \frac{1}{a^{m} }

Evaluating from the inside parenthesis outwards

(-\frac{1}{3}) ^{2} = - \frac{1}{3} × - \frac{1}{3} = \frac{1}{9} , then

(\frac{1}{9}) ^{-2} = \frac{1}{9^{-2} } = 9² = 81 , then

(81)^{-1} = \frac{1}{81}
