Multiply or divide as indicated. x^-8 • x^-2

gladu [14]

ANSWER

$\frac{1}{ {x}^{10} }$

EXPLANATION

The given exponentiial expression is

${x}^{ - 8} \bullet {x}^{ - 2}$

We simplify using the rule:

${a}^{m} \times {a}^{n} = {a}^{m + n}$

We apply this property to get:

${x}^{ - 8} \bullet {x}^{ - 2} = {x}^{ - 8 + - 2}$

We simplify to get;

${x}^{ - 8} \bullet {x}^{ - 2} = {x}^{ - 10}$

We rewrite as a positive index to get;

${x}^{ - 8} \bullet {x}^{ - 2} = \frac{1}{ {x}^{10} }$

Show work for this fraction 1 2/3-3/4

statuscvo [17]

$1\frac23-\frac34$

Write 1 2/3 as an improper fraction...
1 = 3/3. Plus the 2/3 makes 5/3.

$\frac53-\frac34$

To add/subtract fractions, they need the same denominator. (bottom number)

We can change the denominator by multiplying the top and bottom of a fraction by the same number. (it will stay equal, like 1/2 and 2/4)

Let's change 5/3 and 3/4 to a denominator of 12.

5/3 = 20/12 (bottom multiplies by 4, so does the top)
3/4 = 9/12 (bottom multiplies by 3, so does the top)

$\frac{20}{12}-\frac9{12}$

Now we just subtract the 20 minus 9 twelfths. (the twelfths act as a sort of unit)

$\boxed{\frac{11}{12}}$
