Equivalent expressions are expressions that have the same value.

The equivalent expression of [tex]g^{-3}h[/tex] is: [tex]\frac{h}{g^3}[/tex]

The expression is given as;

[tex]g^{-3}h[/tex]

Apply law of indices to change the exponents

[tex]g^{-3}h = \frac{1}{g^3}h[/tex]

Express as products

[tex]g^{-3}h = \frac{1}{g^3} \times h[/tex]

Rewrite as

[tex]g^{-3}h = \frac{h}{g^3}[/tex]

Hence, the equivalent expression is: [tex]\frac{h}{g^3}[/tex]

Hello loll6591!

[tex] \huge \boxed{\mathbb{QUESTION} \downarrow}[/tex]

Perform the indicated operation and simplify the result. x/5+x/6

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

[tex] \frac{x}{5} + \frac{x}{6} \\ [/tex]

First, find the LCM of 5 & 6, which is 30.

[tex] \rightarrow \frac{x}{5} \times \frac{6}{6} = \frac{6x}{30} \\ \\ \rightarrow\frac{x}{6} \times \frac{5}{5} = \frac{5x}{30} [/tex]

Now add 6x/30 with 5x/30.

[tex] \frac{6x}{30} + \frac{5x}{30} \\ = \frac{6x + 5x}{30} \\ = \large \boxed{\boxed{\frac{11x}{30} }}[/tex]

Step-by-step explanation:

Answer:

75% of 60 = 45

Step-by-step explanation:

In order to find the answer to this question you need to divide the percentage of the number by one-hundred and then divide that number by the number the number you are trying to find the percentage of.

60/x=100/75

(60/x)*x=(100/75)*x        

60=1.33333333333*x      

(1.33333333333) to get x

60/1.33333333333=x

45=x

x=45

75% of 60 = 45

Answer:

Step-by-step explanation:

The marked price is 39.98

The tax is 4.5%

That means that the tax is added on to the marked price to get the selling price.

One way to do is is to multiply by the tax factor.

The tax factor is 1 + 4.5/100 = 1.045

So the Selling price = 39.98 * 1.045

Selling price = 41.78 rounded to 2 decimal places.

The more standard way of doing this is to multiply the tax by the marked price and add that on to the marked price to get the selling price.

39.98 * 4.5/100  = 1.7991

39.98

  1.7991        Add

41.7791

The difference comes in where you do the rounding. The second way to do this has no rounding. If you convert this to money, the answer will be 41.78, just as the first way's answer.

Answer:

p(- 3) = - 79

Step-by-step explanation:

Substitute x = - 3 into p(x) , that is

p(- 3) = 4(- 3)³ + 2(- 3)² - 3(- 3) + 2

        = 4(- 27) + 2(9) + 9 + 2

       = - 108 + 18 + 11

      = - 108 + 29

     = -  79
