The number 3 equals x when it has the same value in an equation. This is used to help solve a specific problem in math where certain variables are unknown.
3 x 3 x 3 x 3 = 81. 4^3= 64. So no, they are not equal.
No, it is most definitely not. As long as they are not equal to zero In the sum x-3 you have two components. x (positive) and -3. Likewise in 3-x you have: 3 and -x However if both equal to 0 x will equal 3 in both sums. In the context of your question, they are not the same.
X x 1/3 = x/3
Equation: x+3=3+x (notice the equal sign: equal; equation)Expression: x+3 (notice no equal sign)
Equation: x+3=3+x (notice the equal sign: equal; equation)Expression: x+3 (notice no equal sign)
86.82 x 10^3 is equal to 86,820.
If: 75/x = 25 Then: x = 3
3 x 3 x 3 = 27
3 x 413 = 1239
174 x 3 =522
9 x 9 x 9 3 x 3 x 3 x 3 x 3 x 3
3 x 3 x 2 x 1 is equal to 18.
