Answer
a.
$3^{8}.3^{5} = 3^{13} = 1594323$
b.
$6^{0}.6 = 6$
c.
$(5^{4})^{2} = 5^{8} = 390625$
Work Step by Step
a.
$3^{8}.3^{5} = 3^{8+5} = 3^{13} = 3\times3\times3\times3\times3\times3\times3\times3\times3\times3\times3\times3\times3 = 1594323$
b.
$6^{0}.6 = 1\times6= 6$
c.
$(5^{4})^{2} = 5^{4\times2} = 5^{8} = 5\times5\times5\times5\times5\times5\times5\times5 = 390625$
