How to solve for x with a fraction exponent
WebMar 23, 2024 · First, move everything that isn't under the radical sign to the other side of the equation: √ (2x+9) = 5. Then, square both sides to remove the radical: (√ (2x+9)) 2 = 5 2 =. 2x + 9 = 25. Now, solve the equation as you normally would by combining the constants and isolating the variable: 2x = 25 - 9 =. 2x = 16.

WebAug 3, 2013 · This is because of the order of operations. by typing 2/3^2, you told the calculator to calculate 2 divided by 3 to the power of 2, rather that 2/3 to the power of 2. The order of operations makes it that you calculate exponents before division. To get the right answer, you should input: (2/3)^2. Also (2/3)^2 is 4/9, not 8/27. That is (2/3)^3. WebPart I.
