a) \(2^3\cdot2^4\cdot2^5\cdot2^6\cdot2^7\cdot2^8\cdot2^9\cdot2^{10}\)

\(=2^{3+4+5+6+7+8+9+10}\)

\(=2^{52}\)

b) \(3^2\cdot3^3\cdot3^4\cdot3^5\)

\(=3^{2+3+4+5}\)

\(=3^{14}\)

c) \(4^2\cdot4^3\cdot4^4\)

\(=4^{2+3+4}\)

\(=4^9\)

d) \(5^2\cdot5^3\cdot5^4\)

\(=5^{2+3+4}\)

\(=5^9\)

a)  B   =   3 3 . 3 2   + 2 2   + 3 2 = 256 = 16 2 .

b)  D   =   5 . 4 3   +   2 4 . 5 = 400 =  20 2
