Which of the following has a value of 84?
a. 83
b. 512
c. 32
d. 4,096

Based on the choices, I think the 84 in the problem is not really the number 84. Instead, it is 8 raised to the power of 4 or 8⁴

Thus, 8⁴ = 8 x 8 x 8 x 8 = 4,096

    8 x 8 = 66
  64 x 8 = 512
512 x 8 = 4,096

So, my answer is d. 4,096

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
