How do you know the correct order in which to evaluate algebraic expressions?

To evaluate algebraic expressions there is no order. You just need to follow something called pemdas. The way to remember this is
 
p = please
e = excuse
m = my
d = dear
a= aunt
s = sally
 
So just remember Please excuse my dear aunt sally or pemdas.
   
P = parentheses (Apply from left tor right)
E = exponent (Apply from left tor right)
M = multiplication (Apply from left tor right)
D = division (Apply from left tor right)
A = addition (Apply from left tor right)
S = subtraction (Apply from left tor right)
 
Then solve!
 
Hope this helps!! xD

In solving algebraic expressions, there is an order in which to solve it.

1) perform the operation inside the parenthesis first  
2) then perform the operation with the exponents
3) apply multiplication and division from left to right of the equation.
4) apply addition and subtraction from left to right of the equation.

Remember this: PEMDAS for easier recall. (parenthesis, exponents, multiplication, division, addition, subtraction)

What is 3^(3/2) equal to
Delicious77 [7]
It equals 5.1962.... If it's 3/2 then you can do 3 divided by 2 and you'll get 1.5. If you have a scientific calculator you can do 3 to the power of 1.5 which will get you your answer.

A cubed-shaped box has its side lengths decreased by 3 cm, when this happens, the volume decreases by 1385cm^3. What is the side
mixer [17]

Answer:

Step-by-step explanation:

let side of cube=x cm

volume=x³ cm³

again side=(x-3) cm

volume=(x-3)³ cm³

x³-(x-3)³=1385

(a³-b³)=(a-b)(a²+ab+b²)

(x-x+3){x²+x(x-3)+(x-3)²}=1385

3(x^2+x²-3x+x²-6x+9)=1385

3(3x²-9x+9)=1385

9x²-27x+27=1385

9x²-27x+27-1385=0

9x²-27x-1358=0

x=\frac{27\pm\sqrt{(-27)^2-4*9*(-1358)} }{2*9} \\x=\frac{27\pm\sqrt{729+48888} }{18} \\or~x=\frac{27\pm\sqrt{49617} }{18} \\or~x=\frac{27\pm 222.749}{18} \\taking positive side only as negative sign gives negative length.\\or~x=\frac{27+222.749}{18} \\or~x\approx13.87
