Let's deal with each factor in the numerator individually first: when evaluating the power of a power, you have to multiply the exponents: 
So, we have
^{-\frac{1}{2}} = 3^{2\cdot(-\frac{1}{2})} = 3^{-1},\quad (9^4)^{-1} = 9^{-4}](https://tex.z-dn.net/?f=%20%5Btex%5D%283%5E2%29%5E%7B-%5Cfrac%7B1%7D%7B2%7D%7D%20%3D%203%5E%7B2%5Ccdot%28-%5Cfrac%7B1%7D%7B2%7D%29%7D%20%3D%203%5E%7B-1%7D%2C%5Cquad%20%289%5E4%29%5E%7B-1%7D%20%3D%209%5E%7B-4%7D)
Now remember that 
and 
to rewrite the expression as
Now use the rules

Step-by-step explanation:
The expression is 
. To find the value, substitute the values x = 3 and y =-2 then follow order of operations.
Answer:
The original amount of the mortgage was $66231.45.
Step-by-step explanation:
In order to find the original amount of the mortgage, you can use the following formula to calculate the present value:
PV=FV/(1+r/n)^nt
PV=present value
FV=future value= 775*12*12=111.600
r=rate of interest=0.0440
n= number of compounding periods= 2
t= time in years=12
Now, you can replace the values on the formula:
PV=111600/(1+(0.0440/2))^2*12
PV=111600/(1.022)^24
PV=111600/1.685
PV=66231.45
According to this, the answer is that the original amount of the mortgage was $66231.45.
5x- SR 40= 0., add to the other side, 5x= SR 40. divide both sides by 5, x= SR of 8, or 2 SR 2
