2x = 5
then x*ln(2) = ln(5)
so that x = ln(5)/ln(2) = 2.3219 approx.

What is x in the equation 5 to the power of x equals 5000?
5 to the 5.23231 power
If x equals yz find the value for x given that y equals 2 and z equals 5?
x=2*5 x=10
2 plus 3 to the second power x 2 equals?
If 2+3 5s 5 squared is 25 then 25 times 2 equals 50
What is X to the power of 2 minus 8 X plus 15 equals 0?
It is a quadratic equation and its solutions are: x = 3 and x = 5
Negative x to the second power plus positive x to the second power equals what?
It equals 0. * * * * * Unless the question is (-x)2 + (+x)2. In that case, the answer is 2x2
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.
How do you solve 2a to the power of 8b-5 if a to the power of 2b equals 5?
If you mean 2a8b - 5 = x and a2b = 5, then: 2(54) - 5 = x x = 1350 - 5 x = 1345
What is x in the equation 5 to the power of x equals 5000?
5 to the 5.23231 power
Is y equals x squared 2 plus 5 linear?
No, to be linear, both the power of x and y need to be 1. Since x is squared, the power of x is 2.
What is 5-x equals 7?
5-x equals 7 = -2
If x equals yz find the value for x given that y equals 2 and z equals 5?
x=2*5 x=10
What is x when x to the power of 5 equals 24?
x = about 1.888175023
What is 5 to the x power equals 17?
x = 1.762340347832317
What is x to the power of 5 equals 343?
x = 3.2140958497160386
2 plus 3 to the second power x 2 equals?
If 2+3 5s 5 squared is 25 then 25 times 2 equals 50
What is y equals x plus 2 when x equals -1 and y equals 5?
If [ y = x + 2 ], then x is not -1 when y = 5.If [ y = x + 2 ],then when x = -1, y = 1,and when y = 5, x = 3.
If x squared y squared equals 25 xy equals 5 prove that x over y plus y over x equals 5 somebody HELP?
x/y = 5/(y^2) and y/x = 5/(x^2). So x/y + y/x = 5/(y^2) + 5/(x^2), which equals 5x^2/(x^2 y^2) + 5y^2/(x^2 y^2) equals 5(x^2 + y^2)/25 equals (x^2 + y^2)/5. x^2 = 25/y^2, so you get (25/y^2 + y^4/y^2)/5 equals ((25 + y^4)/y^2)/25, which shows that your math teacher is on crack. Seriously, I'm not sure that's true.
