Step 1: Rewrite the expression by separating terms with the same base.
ab2a3b5=a1a3×b2b5
Step 2: Apply the law of indices for division, which states that xnxm=xm−n.
For the terms with base a:
a1a3=a3−1=a2
For the terms with base b:
b2b5=b5−2=b3
Step 3: Combine the simplified terms.
a2×b3=a2b3
The final answer is a2b3.
