Question

Answer 1

a: \(7^5\cdot2^5=\left(7\cdot2\right)^5=14^5\)

b: \(16^4\cdot2^7=2^{16}\cdot2^7=2^{23}\)

c: \(8^2:49^3=\dfrac{2^6}{7^6}=\left(\dfrac{2}{7}\right)^6\)

d: \(0,3^3\cdot70^3=\left(0,3\cdot70\right)^3=21^3\)

e: \(\left(\dfrac{8}{7}\right)^8\cdot\dfrac{64}{49}=\left(\dfrac{8}{7}\right)^8\cdot\left(\dfrac{8}{7}\right)^2=\left(\dfrac{8}{7}\right)^{10}\)

f: \(\left(\dfrac{3}{5}\right)^4:\dfrac{9}{25}=\left(\dfrac{3}{5}\right)^4:\left(\dfrac{3}{5}\right)^2=\left(\dfrac{3}{5}\right)^2\)
