Help me solve the practice problem please​

Since 3^5 is 243, all you have to do is 243*6 :)

Step-by-step explanation:

We are given 3^5 = 243. Exponents work in the way of 3^5 = 3*3*3*3*3, essentially multiplying the base by itself by the number of the exponent. Knowing this, we realize that 3^6 is just 3^5*3, so we can quickly and easily calculate that 3^6 = 729.

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)
