a: \(A=\left(2^3\right)^2\cdot\left(2^5\right)^4=2^6\cdot2^{20}=2^{26}\)
b: \(=\left(3^3\right)^3\cdot\left(3^2\right)^4\cdot3^5=3^9\cdot3^8\cdot3^5=3^{22}\)
\(A=8^2.32^4=\left(2^3\right)^2.\left(2^5\right)^4=2^6.2^{20}=2^{26}\)
\(B=27^3.9^4.243=\left(3^3\right)^3.\left(3^2\right)^4.3^5=3^9.3^8.3^5=3^{22}\)

a ) \(A=8^2.32^4=\left(2^3\right)^2.\left(2^5\right)^4\)
\(=2^6.2^{20}\)
\(2^{6+20}=2^{26}\)
b ) \(B=27^3.9^4.243=\left(3^3\right)^3.\left(3^2\right)^4.3^5\)
\(=3^9.3^8.3^5=3^{9+8+5}\)
\(=3^{22}\)
a) A= 8^2 . 32^4
= (23)2 . (25)4
= 2^6 . 2^20 = 2^26
b) B= 27^3 . 9^4 . 243
= (3^3)^3 . (3^2)^4 . 3^5
= 3^9 . 3^8 . 3^5
=3^22
