Answers:
Part A: The value of x must be 0
Part B: The value of x can be any real number
----------------------------------------------------------------
Explanation:
Part A) We have the equation (7^2)^x = 1 which simplifies to 7^(2x) = 1. The only way to get the left side equal to the right side is to have the exponent of 2x equal zero. If 2x = 0, then x = 0. So that's why x = 0 is the only solution here.
--------------
Part B) Similar to part A above, but the exponent is slightly different now. We have (7^0)^x = 1 which turns into 7^(0*x) = 1. The exponent 0*x is really 0 no matter what x is. We can plug in any real number we want for x and the left side will always be 1. This is why the solution set to this equation is the set of all real numbers.
since there is 5 numbers less than 6, the first time it will be 5/10 or 1/2 and then they dont get replaced meaning that the second time it is 4/9 which then when they are multiplied it is 1/2*4/9 which is 4/18 or 2/9 so the answer is 2/9
X² - 6x - 9 = 0
x² - 3x - 3x - 9 = 0
x (x-3) -3(x + 3) = 0
(x - 3)² = 0
In short, Your Answer would be Option A
Hope this helps!
