Answer/Step-by-step explanation:

The following steps to solve equation given by join are shown below including the property of numbers applied for each reasons:

4(2a + 3) = -3(a - 1) + 31 - 11a ----› Given

Apply the distributive property to open the parentheses

4*2a + 4*3 = -3*a -3*-1 + 31 - 11a

8a + 12 = -3a + 3 + 31 - 11a ----› Distributive property

Combine like terms together

8a + 12 = 3 + 31 -3a - 11a

8a + 12 = 34 - 14a ---› Combining like terms

Add 14a to both sides

8a + 12 + 14a = 34 - 14a + 14a

22a + 12 = 34 ----› Addition property

Subtract 12 from both sides

22a + 12 - 12 = 34 - 12

22a = 22 ----› subtraction property of equality

Divide both sides by 22

22a/22 = 22/22

a = 1 ----› Division property of Equality

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} }
