Jawapan:

E

Penjelasan:

# (b ^ 3root (3) (a ^ 2b ^ 5)) / a # inilah soalan anda kelihatan seperti

Peraturan 1: # a ^ -1 = 1 / a ^ 1 = 1 / a #

Peraturan 2: # sqrtx = x ^ (1/2) #

# (b ^ 2 (a ^ 2b ^ 5) ^ (1/3)) / a #

Peraturan 3: #sqrt (ab) = sqrtasqrtb = (ab) ^ (1/2) = a ^ (1/2) b ^ (1/2) #

# (b ^ 2a ^ (2/3) b ^ (5/3)) / a #

Peraturan 4: # a ^ 2 * a ^ 3 = a ^ (2 + 3) = a ^ 5 #

Kaedah 5: # a ^ 2 / a ^ 3 = a ^ (2-3) = a ^ -1 #

# b ^ (2 + 5/3) a ^ (2 / 3-1) = b ^ (6/3 + 5/3) a ^ (2 / 3-3 / 3) = b ^ (11/3) a ^ (- 1/3) = b ^ (11/3) / a ^ (1/3) #

Jadi jawapannya adalah E
