Answer 1

a: \(=\left(\dfrac{1}{2}\right)^3\cdot\left(\dfrac{1}{2}\right)^4=\left(\dfrac{1}{2}\right)^7\)

b: \(=\left(-\dfrac{1}{2}\cdot\dfrac{2}{5}\right)^2=\dfrac{1}{25}\)

c: \(=\left(\dfrac{5}{4}:\dfrac{-35}{24}\right)^2=\left(-\dfrac{5}{4}\cdot\dfrac{24}{35}\right)^2=\left(-\dfrac{6}{7}\right)^2=\dfrac{36}{49}\)

d: \(=5^6\)
