a) \(3^7:3^6+\left(\dfrac{5}{17}\right)^0\)

\(=3^{7-6}+1\)

\(=3^1+1\)

\(=4\)

b) \(\left(\dfrac{5}{2}\right)^{13}:\left(\dfrac{1}{2}+2\right)^{12}\)

\(=\left(\dfrac{5}{2}\right)^{13}:\left(\dfrac{5}{2}\right)^{12}\)

\(=\left(\dfrac{5}{2}\right)^{13-12}\)

\(=\dfrac{5}{2}\)

\(a)\)\(3^7:3^6+\left(\dfrac{5}{17}\right)^0\)

\(=3^{7-6}+1\)

\(=3^1+1\)

\(=3+1=4\)

\(b)\)\(\left(\dfrac{5}{2}\right)^{13}:\left(\dfrac{1}{2}+2\right)^{12}\)

\(=\left(\dfrac{5}{2}\right)^{13}:\left(\dfrac{5}{2}\right)^{12}\)

\(=\left(\dfrac{5}{2}\right)^{13-12}\)

\(=\left(\dfrac{5}{2}\right)^1=\dfrac{5}{2}\)
