9^(3/2)*10^(2n)^(3/2)=27*10^(3n)
John's gross monthly salary is $2000.
John receives a 15% raise in his salary.
So first we have to find 15% of $2000.
15% of 2000 = 
= 
= 
= 
John's salary including the raise = $
= $2300.
Now 30% of his monthly paycheck withheld for taxes.
30% of 2300 = 
= 
= 
= 
So the amount of tax deducted = $690.
John's net monthly income = $
= $1610.
So we have got the required answer.
26.38
5.5%=.055
.055x25=1.375(1.38)
25+1.38=26.38

Evaluate the expression 4(2x+y)-2y+z for x=-2, y=4 and z=-3

Before inserting the values of the variables, I recommend writing the equation in its simplest form.
First, use the distributive property and distribute 4:-
8x+4y-2y+z
Simplifying,
8x+2y+z
Now that the expression is in its simplest form, we can substitute the variables and simplify the expression.
First, write -2 in lieu of x:-
8(-2)+2y+z
-16+2y+z
Now, write 4 in lieu of y:-
-16+2(4)+z
-16+8+z
-8+z
Final step:-
write -3 in lieu of z:-
-8+(-3)
-8-3
-11
