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. Factor out the greatest common factor ( GCF) from each group. These values should afford the following polynomial equation: y 2x4 + 9x3 + 6x2 + 8x1 + 3x0 is the unique the solution of the linear system of equations. Group the first two terms and the last two terms. (-2.80) 2 and (+2.80) 2 are both positive we don’t need to check +2.80 separately.Īpply the change of base formula to switch from base 5 to base 10. Factor out the greatest common factor from each group. Round to the nearest hundredth.Ĭheck your answer by substituting the value of x into the original equation. Don’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. Rewrite this logarithmic equation as an exponential equation.
