Can you please help me with my homework and I have a picture of it

Given expression :

▪︎9 × (3³ - 7) ÷ 2

Let us evaluate this expression :

Thus, the final answer after evaluating the expression = 9

▪︎Therefore, 9 × (3³ - 7) ÷ 2 = 9

50

Step-by-step explanation:

9 x (3^3 - 7) / 2 - 40

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)
