44
Does 2 x 2 x 7 equals 56?
No, it equals 28.
How do you solve x-2 equals 7?
x-2=7 x=7+2x=9dips**t
What is the value of 2x3 plus 15yif x equals -7 and y equals 2?
x = -7, y = 2 ⇒ 2x3 + 15y = 2 x (-7)3 + 15 x 2 = 2 x (-343) + 15 x 2 = -656
What is the value of 7 to the power of 2 plus 2x when x equals 3?

Is -7 raised to the power of 3 equals to -7 raised to the power of 3?
Reflexivity is a property of equality, i.e., X = X is always true. Thus -7 raised to the power of 3 equals -7 raised to the power of 3 is true.
Does 2 x 2 x 7 equals 56?
No, it equals 28.
What does squared x equal 7?
2.645 squared equals 7. Save --------- Unclear what you're asking: If x=7, then x^2 (that is, "x squared") equals 49. or If x^2=7, then x equals the square root of 7, or about 2.64575

What is x--5 equals 7?
x = 2
If x to the power 4 plus 1 upon x to the power 4 equals 47 then what will be x to the power 3 plus 1 upon x to the power 3 equals what?
A similar question can be solved as below : If x to the power 4 plus 1 upon x to the power 4 equals 23 then what will be (x minus 1 upon x) to the power 2 equals what?a2 + b2 = (a + b)^2 - 2ab.so (x^2 )^2 + (1/x2)^2 = (x^2 + 1/x^2)^2 - 2 = 23.so (x^2 + 1/x^2) = 5.therefore(x - 1/x)^2 = (x^2 + 1/x^2) -2 = 5 -2 = 3.
