The duration to triple the amount.Given: Interest is 8\% compouned annually.

To calculate:
To simplify ${\displaystyle -6x^2-(-2x^2)}$.

To calculate the expression ${\displaystyle \sqrt{\frac{5}{32}}}$.

While using Cost-benefit analysis which of the following is a true statement.
a) It will always produce a recommendation consistent with the simple payback period method.
b) It will always produce a recommendation consistent with the present worth, future worth, and annual worth methods.
c) It can be used only to evaluate projects from the public sector (such as bridges and roadways).
d) None of the above.

Rewrite the rational exponent as a radical by extending the properties of integer exponents. ${\displaystyle 2\frac{7}{8}}$ divided by ${\displaystyle 2\frac{1}{4}}$.

Rewrite the following exponential expressions as equivalent radical expressions. If the number is rational, write it without radicals or exponents.
${\displaystyle {27}^{-\frac{2}{3}}}$

To simplify the expression ${\displaystyle {25}^{\frac{1}{2}}}$

We need to calculate: The simplified value of the radical expression $\sqrt[3]{\sqrt[3]{2a}}$
