Factor completely. $$-x^{2}-4 x+5$$
Factor and simplify each algebraic expression. $$\left(x^{2}+4\right)^{\frac{1}{2}}+\left(x^{2}+4\right)^{\frac{7}{2}}$$
Simplify by reducing the index of the radical. $$ \sqrt[6]{x^{4}} $$
You had \(\$10,000\) to invest. You put x dollars in a safe, government-insured certificate of deposit paying 5% per year. You invested the remainder of the money in noninsured corporate bonds paying 12% per year. Your total interest earned at the end of the year is given by the algebraic expression $$0.05 x+0.12(10,000-x)$$ a. Simplify the algebraic expression. b. Use each form of the algebraic expression to determine your total interest earned at the end of the year if you invested $6000 in the safe, government-insured certificate of deposit.
Simplify each expression. Assume that all variables represent positive numbers. $$ \left(\frac{x^{\frac{1}{2}} y^{-\frac{7}{4}}}{y^{-\frac{5}{4}}}\right)^{-4} $$
