Answer:
343 or 7^3
Step-by-step explanation:
7^8/5 × 7^-3/5 × 7^2
=note - If we have same base and diff powers, and the bases are being multiplies like in the question, we add the powers.
so,
=>7^8/5 × 7^-3/5 × 7^2
=> (7)^[8/5 +(-3/5) + 2]
=> (7)^(8/5 - 3/5 +2)
=>(7)^( 5/5 +2)
=> (7)^(1+2)
=>(7)^3
=> 343
