Answer:
<h3>The correct option is option (c).</h3>
Step-by-step explanation:
Factor: The smallest divisor of function is the factors of the function.
26r³s = 13×2×r×r×r×s
52r⁵= 13×2×2×r×r×r×r×r
39r²s⁴ = 13×3×r×r×s×s×s×s
The common factors are = 13×r×r =13r²
Therefore
26r³s+52r⁵-39r²s⁴
=( 13×2×r×r×r×s)+(13×2×2×r×r×r×r×r)-(13×3×r×r×s×s×s×s)
=13r²(2×r×s+2×2×r×r×r-3×s×s×s×s)
=13r²(2rs+4r³-3s⁴ )
∴26r³s+52r⁵-39r²s⁴ =13r²(2rs+4r³-3s⁴ )
