According to the meaning of power, the quadratic power of 4 = 4 * 4, the cubic power of 4 = 4 * 4 * 4, then the cubic power of 4 quadratic power * 4 = (4 * 4) * (4 * 4 * 4) = 4 * 4 * 4 * 4 = 4 Then the cubic power of 4 quadratic power * 4 = (4 * 4) * (4 * 4 * 4) = the quintic power of 4 * 4 * 4 * 4 = 4, so as to calculate the m power of a and the n power of a (m, n is an integer)

M power of a = a * a... A * a (m a multiplied)
The nth power of a = a * a... A * a (multiply n a)
M power of a * n power of a
=(a*a...a*a)*(a*a...a*a)
=A * a... A * a * a * a... A * a [(M + n) a multiplied]
=The (M + n) power of a
