Question

Solve each equation or inequality. Write solutions to inequalities in interval notation.If no solution exists, write no solution.Number 10

Answer 1

Case: Inequality

Method:

`\begin{gathered} 30=3√(x)-12 \\ 30+12=3√(x) \\ 42=3√(x) \\ (42)/(3)=(3√(x))/(3) \\ 14=√(x) \\ square\text{ }b.s \\ 14^2=(√(x))^2 \\ x=196 \end{gathered}`

Final answer:

x= 196
