Webx 1 = − 2.96139 x 2 = − 2.96136 which is the solution for six significant figures. Let us apply it to the second root starting using x 0 = 1.5; the iterates will be x 1 = 1.35215 x 2 = 1.33529 x 3 = 1.33509 which is the solution for six significant figures.
WebWe can solve equations in which a variable is raised to a rational exponent by raising both sides of the equation to the reciprocal of the exponent. The reason we raise the equation to the reciprocal of the exponent is because we want to eliminate the exponent on the variable term, and a number multiplied by its reciprocal equals 1. earthrise petalumaWebTo solve exponential equations without logarithms, you need to have equations with comparable exponential expressions on either side of the "equals" sign, so you can compare the powers and solve. ... and solve the resulting equation.
