Answer:
dfthfgttttttttttttttttttttttttttttttttttttttttttttttttttttttttttth
Step-by-step explanation:
We have that
8=2*2*2
108=2*2*3*3*3
then
√(8/108)=√(2*2*2)/(2*2*3*3*3)=√(2)/(3*3*3)=(1/3)*√(2/3)
the answer is (1/3)*√(2/3)
Answer:
63
Step-by-step explanation:
Follow PEMDAS, as well as the left -> right rule.
Note that PEMDAS is the order of operations in which you should solve, and =
Parenthesis
Exponents (& roots)
Multiplication
Division
Addition
Subtraction.
First, look at the problem. The problem gives you:
42 ÷ 2 x (11 - 8)
Using PEMDAS, first, solve the parenthesis:
11 - 8 = 3
Next, use the left -> right rule to solve the rest.
42 ÷ 2 x 3
(42 ÷ 2) x 3
(21) x 3 = 63
63 is your answer.

Answer:
t=2x-2/-2x-5
Step-by-step explanation:
y=-2x-5
ty= 2x-2
add the y value in
t-2x-5=2x-2
combine like terms
t=4x+3
hope this helps :)
