Explanation:
To multiply fractional exponents with the same base, we have to add the exponents and write the sum on the common base. The general rule for multiplying exponents with the same base is a1/m × a1/n = a(1/m + 1/n). For example, to multiply 22/3 and 23/4, we have to add the exponents first. So, 2/3 + 3/4 = 17/12.
