唔識計...help me pls~
If m and n are integers, decide whether each of the following statements is always correct.
e) 5^(n) X 5^(n) = 5^(2n)
f) 5^(n) X 5^(n) = 5^(n^(2))
g) 5^(n) X 5^(n) = 25^(n)
h) 5^(n) X 5^(n) = 2(5^(n))
i) 5 X 5^(n) = 25 ^(n)
j) 5 X 5^(n) = 5^(n+1)
l) 15^(m)/3^(n) = 5^(m-n)
m) 15^(m) / 15 ^(n) = 15 ^(m-n)
要寫step...
唔該晒~
