Question

simplify a^-5/7×a^-7/5​

Answer 1

Answer:

a^-74/35

Step-by-step explanation:

The property says a^m×a^n =a^m+n

a^-5/7×a^-7/5

=a^-5/7+(-7/5)

=a^-25/35-49/35

a^-74/35

=a^-74/35

Answer 2

Step-by-step explanation:

${a}^{m} \times {a}^{n} = {a}^{m + n}$

${a}^{ \frac{ - 5}{7} } \times {a}^{ \frac{ - 7}{5} } = {a}^{ \frac{ - 5}{7} + \frac{ - 7}{5} } \\ {a}^{ \frac{ - 25 - 35}{35} } \\ {a}^{ \frac{ - 70}{35} } \\ {a}^{2}$

So the answer to this question is a^2
