Answer:

p^{-1}q^{4}r^{8}.

Step-by-step explanation:

The given expression is \frac{p^{-4}q^5r^6}{p^{-3}qr^{-2}}.

Recall and use the following rule of exponents;

\frac{a^m}{a^n}=a^{m-n}

We apply this rule to obtain:

p^{-4--3}q^{5-1}r^{6--2}

p^{-4+3}q^{4}r^{6+2}.

This simplifies to:

p^{-1}q^{4}r^{8}.

Since we do not want to leave any factor in the denominator, the required answer is:

p^{-1}q^{4}r^{8}.

Answer: \frac{q^4r^8}{p}

Step-by-step explanation:

By the Negative exponent rule, we know that:

a^{-1}=\frac{1}{a}

By the Quotient of powers property, we know that:

\frac{a^m}{a^n}=a^{(m-n)

And by the Product of powers property, we know that:

(a^m)(a^n)=a^{(m+n)}

Applying this properties, we get:

\frac{p^{-4}q^5r^6}{p^{-3}qr^{-2}}=\frac{p^3q^5r^6r^2}{p^4q}=\frac{q^4r^8}{p}

Consider the differential equation x^2 y''-xy'-3y=0. If y1=x3 is one solution use redution of order formula to find a second lin
Anastasy [175]

Suppose y_2(x)=y_1(x)v(x) is another solution. Then

\begin{cases}y_2=vx^3\\{y_2}'=v'x^3+3vx^2//{y_2}''=v''x^3+6v'x^2+6vx\end{cases}

Substituting these derivatives into the ODE gives

x^2(v''x^3+6v'x^2+6vx)-x(v'x^3+3vx^2)-3vx^3=0

x^5v''+5x^4v'=0

Let u(x)=v'(x), so that

\begin{cases}u=v'\\u'=v''\end{cases}

Then the ODE becomes

x^5u'+5x^4u=0

and we can condense the left hand side as a derivative of a product,

\dfrac{\mathrm d}{\mathrm dx}[x^5u]=0

Integrate both sides with respect to x:

\displaystyle\int\frac{\mathrm d}{\mathrm dx}[x^5u]\,\mathrm dx=C

x^5u=C\implies u=Cx^{-5}

Solve for v:

v'=Cx^{-5}\implies v=-\dfrac{C_1}4x^{-4}+C_2

Solve for y_2:

\dfrac{y_2}{x^3}=-\dfrac{C_1}4x^{-4}+C_2\implies y_2=C_2x^3-\dfrac{C_1}{4x}

So another linearly independent solution is y_2=\dfrac1x.

Mr. Layte needs a mortgage to buy his first house. Which describes how this will affect Mr. Layte's financial situation?
Norma-Jean [14]

9514 1404 393

Answer:

  A, D

Step-by-step explanation:

Assuming that Mr. Layte must pay for his mortgage from his (otherwise) disposable income, that disposable income will decrease. As in choice A, there will likely be additional ownership expenses besides the mortgage. Under our assumption, Mr. Layte's disposable income does not remain the same or increase.

The appropriate choices are A and D: the amount of money he has to spend on things will decrease ...
