Use the rules of significant figures to find the answer to the addition problem S= 25.4+14+16.67+3.903
xenn [34]
S=59.973 all you have to do now is round it. So the real answer is S=60. All i did was add up all the numbers.
25.4 + 16.67 = 42.07 + 3.903 = 45.973 + 14 = 59.973

Find the derivative using composition of functions of <br><img src="https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%20%7Bx%7D%5E%7B
sergeinik [125]
\bf \sqrt[3]{x^2}\implies \left(\stackrel{outer~function}{\left( \stackrel{inner~function}{x} \right)  }\right)^{\frac{2}{3}}\implies \stackrel{\qquad  \qquad  chain~rule}{\stackrel{outer}{\cfrac{2}{3}x^{-\frac{1}{3}}}}\cdot \stackrel{inner}{1}&#10;\\\\\\&#10;\cfrac{2}{3x^{\frac{1}{3}}}\implies \cfrac{2}{3\sqrt[3]{x}}

so, the function is really a composite function, you could think of it 

\bf \begin{cases}&#10;f(x)=x\\&#10;g(x)=x^{\frac{2}{3}}&#10;\end{cases}\implies g(~~f(x)~~)=(x)^{\frac{2}{3}}
