Answer:
x, log7(x)
1, 0 (B)
7, 1 (D)
49, 2 (E)
1/7, -1 (G)
1/49, -2 (H)
Step-by-step explanation:
Powers of 7 are ...
7^-2 = 1/7^2 = 1/49
7^-1 = 1/7^1 = 1/7
7^0 = 1
7^1 = 7
7^2 = 49
The log (base 7) of the number on the right is the exponent on the left. That is ...
log7(7) = log7(7^1) = 1
log7(1/49) = log7(7^-2) = -2
