Q. −81x^2=−11 What are the solutions to the given equation?
Divide by −81: We are given the equation −81x2=−11. To find the solutions for x, we need to isolate x by performing algebraic operations. The first step is to divide both sides of the equation by −81 to get x2 by itself.Calculation: x2=−81−11
Simplify right side: Simplify the right side of the equation by dividing −11 by −81.Calculation: x2=8111
Take square root: To find the value of x, we need to take the square root of both sides of the equation. Since we are dealing with real numbers, we must consider both the positive and negative square roots.Calculation: x=±8111
Simplify square root: Simplify the square root of the fraction by taking the square root of the numerator and the denominator separately.Calculation: x=±11/81
Final simplification: Since the square root of 81 is 9, we can further simplify the expression.Calculation: x=±11/9
