a: \(=5^5\cdot32=10^5\)
b: \(=5^3\cdot\left(-2\right)^3\cdot\left(-3\right)^3\cdot1=30^3\)
c: \(=\left(-8\right)^5\cdot9^5=-72^5\)

a) = 2^12 . 2^2 . 2^40
= 212+2+40
= 2^54
b)= 3^5 . 3^3 . 3^8
= 35+3+8
= 3^16
c)= 5^4 . 5^2 . 5^3
= 54 + 2 +3
= 5^9
a) 84. 22.1610 = (23)4.22.(24 )10= 212 .22.240=254
b) 35.27.812 = 35.33.( 34) 2 = 35 . 33.38 = 316
c) 252.52.125 =(52)2 .52.53= 54.52.53= 59

a) \(4^3\cdot32^4\)
\(=\left(2^2\right)^3\cdot\left(2^5\right)^4\)
\(=2^6\cdot2^{20}\)
\(=2^{26}\)
b) \(3^{20}\cdot9^{10}\cdot27^2\)
\(=3^{20}\cdot\left(3^2\right)^{10}\cdot\left(3^3\right)^2\)
\(=3^{20}\cdot3^{20}\cdot3^6\)
\(=3^{46}\)
c) \(3^{10}\cdot7^{10}\)
\(=\left(3\cdot7\right)^{10}\)
\(=21^{10}\)
d) \(6^{15}:6^{14}\)
\(=6^{15-14}\)
\(=6\)
e) \(28^3:7^3\)
\(=4^3\cdot7^3:7^3\)
\(=4^3\)
\(=2^6\)
