The two numbers are 31 and 35.

Step-by-step explanation:

Let,

one number = x

2nd number = y

According to statement;

x+y=66 Eqn 1

y=x+4 Eqn 2

Putting y=x+4 from Eqn 2 in Eqn 1;

$x+(x+4)=66\\x+x+4=66\\2x=66-4\\2x=62\\Dividing\ both\ sides\ by\ 2\\\frac{2x}{2}=\frac{62}{2}\\x=31\\Putting\ x=31\ in\ Eqn\ 2\\y=31+4\\y=35$

The two numbers are 31 and 35.

Which expression is equivalent to (4mn/m^-2n^6)^-2

Illusion [34]

First, we get rid of the negative exponent in the parenthesis. We do this by moving it to the top. Our equation is now:

$( \frac{4m^3n}{n^6})^{-2}$

Next, we can cross out one n from both the top and the bottom.

$(\frac{4m^3}{n^5} )^{-2}$

Finally, we evaluate the -2

Our equation becomes:

$\frac{ (4*m^3)^{-2} }{(n^5) ^{-2} }$

This becomes: $\frac{(n^5)^2}{(4*m^3)^2} = \frac{ n^{10} }{16*m^6}$

This can not be simplified any further, so this is the final answer.
