Note: YouвЂ™ll find it helpful to record which properties you use at each step, both to help you be sure youвЂ™re using them properly and as a way to help you find errors. You can use the properties of logarithms to combine these logarithms into one logarithm. The equations may also include more than one logarithm. The check shows that with rounding accounted for, a true statement results, so you know that the answer is correct. (-2.80) 2 and (+2.80) 2 are both positive we donвЂ™t need to check +2.80 separately.ДЄpply the change of base formula to switch from base 5 to base 10. Move all terms not containing x x to the right side of the equation. To solve an equation such as 2 x 6 8 displaystyle 2x - 68 2ењ†8, we notice that the absolute value will be equal to 8 if the quantity. Round to the nearest hundredth.Д¬heck your answer by substituting the value of x into the original equation.

DonвЂ™t forget that when using the square root property, both positive and negative roots must be considered. In this case, divide both sides by 3, then use the square root property to find the possible values for x.
