In Algebraic Expressions in Algebra,x is a variable,meaning, it has no value. But if you do algebra,like 2x-5, you subtract 2 from 5. The answer is 3,right? but 2 is written before 5,so you write -3. You then can copy the x and voila! That is the answer. BTW the answer is -3x.

2x 5x 35 What is x?
In the expression 2x * 5x * 35, x is a variable representing an unknown value. The expression can be simplified by multiplying the coefficients of x together, resulting in 2 * 5 * 35 = 350. Therefore, the value of x itself is not explicitly defined in this context.
-2x 5 -4x 7?
I assume that the question means 4x-7=2x+5. In that case, the answer x would equal 6.
How do you multiply powers with the same exponent?
You multiply the bases, for example, 23 x 53 = 103.The general rule is for real numbers ( but it works for others as well) a and b(ab)n =an bnI think it helps to see why this is true. Look at the example given23 is 2x2x253 is 5x5x5If we multiply these we have2x2x2x5x5x5 which is three 2's and three 5's.Now rearrange them which we can do because of the commutative property ofmultiplication and pair up each 2 with a 5 and here is what you have:(2x5)(2x5)(2x5)this is (2x5)3
