Explain how the Quotient of Powers was used to simplify this expression. 2 to the fifth power, over 8 = 22 By finding the quotie

astraxan [27]

Answer:

we can do it by simplifying 8 to $2^3$ to make both powers base two, and subtracting the exponents.

Step-by-step explanation:

We have been given the expression $\frac{2^5}{8}=2^2$

8 can be rewritten as $2^3$

Hence, the given expression becomes

$\frac{2^5}{2^3}=2^2$

After subtracting the exponents on left hand side of the equation we get:

$2^2=2^2$

we can do it by simplifying 8 to $2^3$ to make both powers base two, and subtracting the exponents.

A=12h(a+b) Solve for h.

nikklg [1K]

Answer:

$h=\frac{A}{12a+12b}$

Step-by-step explanation:

Solve for h, means that you have <em>to clear</em> h.

We have the expression $A=12h(a+b)$

We can divide both sides of the equation in (a+b):

$A=12h(a+b)\\\frac{A}{(a+b)}=\frac{12h(a+b)}{(a+b)}\\\\\frac{A}{(a+b)}=12h$

Now divide again both sides of the equation in 12.

$\frac{A}{(a+b)}=12h\\\\\frac{A}{12(a+b)} =\frac{12h}{12}\\\\\frac{A}{12a+12b} =h$

Observation: Distributive property: $c(a+b)=ca+cb$ , then: $12(a+b)=12a+12b$

The answer is: $h=\frac{A}{12a+12b}$
