Class 8th NCERT - Mathematics Exemplar 8. exponents and powers

Answer :

Let W₁ be the work done by firstmachine.

Let W₂ be the work done by second machine.

Work done by both the machines is W_t = W₁xW₂

W_t = 25² = 625

625 = 5x5x5x5 = 5²x5²

W₁xW₂ = 5²x5²

W₁ = W₂ = 5²

Therefore, Neha can use a hook-up of two (x5²) machines.
