Part A: If (6²)x = 1, what is the value of x? Explain your answer. (5 points)

aleksandr82 [10.1K]

Answer:

A: x = 1/36

B: x = 1

Step-by-step explanation:

Part A:

(6²)x = 1

6² = 36, so we write 36 instead of 6² and get:

36x = 1

Now we divide both sides by 36 to find the value of x.

x = 1/36

Part B:

(6ˆ0)x = 1

6^0 = 1, so we replace 6^0 with 1 in the equation and get:

1x = 1

1x is the same as x, so our solution is:

x = 1

OLga [1]

Step-by-step explanation:

Hey there!

f(x) = 7/x

~ Simply keep the "7" in the place where "x" is there.

$f(7) = \frac{7}{7}$

Therefore, X= 1.
