\(A.4^{10}.2^{30}=\left(2^2\right)^{10}.2^{30}=2^{20}.2^{30}=2^{50}\)

\(B.9^{25}.27^4.81^3=\left(3^2\right)^{25}.\left(3^3\right)^4.\left(3^4\right)^3=3^{50}.3^{12}.3^{12}=3^{74}\)

\(C.25^{50}.125^5=\left(5^2\right)^{50}.\left(5^3\right)^5=5^{100}.5^{15}=5^{115}\)

\(D.64^3.4^8.16^4=\left(2^6\right)^3.\left(2^2\right)^8.\left(2^4\right)^4=2^{18}.2^{16}.2^{16}=2^{50}\)
