Brian tried to solve a math problem on his math homework. here's one of the questions he had to answer. how do you solve 2/3p + 3; p = 3/5? make sure that you show your work!

The answer would be 17/5

Step-by-step explanation:

To solve this, take the original equation and input 3/5 for p.

2/3p + 3

2/3(3/5) + 3

Now complete the multiplication followed by the addition.

2/3(3/5) + 3

2/5 + 3

17/5

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:

60: 45 =12: 9 =4: 3 so the answer is 4: 3
