Question

Use the calculator to evaluate each expression.Round your answers to the nearest thousandth.Do not round any intermediate computations.193.11' = 0-0.8530Х5?

Answer 1

3.1^(1.9) = 8.582

(3/5)^(-0.85) = 1.544

Step-by-step explanation:

Using the calculator and the properties of the exponents, we get that the expressions are equal to

`\begin{gathered} 3.1^(1.9)=8.582 \\ ((3)/(5))^(-0.85)=(0.6)^(-0.85)=(1)/(0.6^(0.85))=(1)/(0.648)=1.544 \end{gathered}`

Therefore, the answers are:

3.1^(1.9) = 8.582

(3/5)^(-0.85) = 1.544
