Do you know what the answer for 3^6 - 5^4= 13x2^a is?

Step-by-step explanation:

since 3⁶ - 5⁴ = 13 × 2ᵃ

then  729 - 625 = 13 × 2ᵃ

⇒                104 = 13 × 2ᵃ

            104 ÷ 13 = 2ᵃ

                       8 = 2ᵃ

                       2³ = 2ᵃ

step-by-step explanation:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
