a) \(3^7:3^6+\left(\dfrac{5}{17}\right)^0\)
\(=3^{7-6}+1\)
\(=3^1+1\)
\(=4\)
b) \(\left(\dfrac{5}{2}\right)^{13}:\left(\dfrac{1}{2}+2\right)^{12}\)
\(=\left(\dfrac{5}{2}\right)^{13}:\left(\dfrac{5}{2}\right)^{12}\)
\(=\left(\dfrac{5}{2}\right)^{13-12}\)
\(=\dfrac{5}{2}\)
\(a)\)\(3^7:3^6+\left(\dfrac{5}{17}\right)^0\)
\(=3^{7-6}+1\)
\(=3^1+1\)
\(=3+1=4\)
\(b)\)\(\left(\dfrac{5}{2}\right)^{13}:\left(\dfrac{1}{2}+2\right)^{12}\)
\(=\left(\dfrac{5}{2}\right)^{13}:\left(\dfrac{5}{2}\right)^{12}\)
\(=\left(\dfrac{5}{2}\right)^{13-12}\)
\(=\left(\dfrac{5}{2}\right)^1=\dfrac{5}{2}\)
a)37:36+(\(\dfrac{5}{17}\))0
=31+1
=4
b)
=(52)13−12=(52)13−12
