Solve the equation for x by combining like terms first.
3x-10+5x=2x-13

Step-by-step explanation:

Combine like terms on left hand side. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.

⟼

Transpose 2x to left hand side and change it's sign.

Similarly , Transpose 10 to right hand side and change it's sign.

⟼

⟼

Divide both sides by 6

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

step-by-step explanation:

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !
