What is Log Base 7 of 70?

The below is the work with steps to find what is log base 7 of 70 shows how the input values are being used in the log base 7 functions. Formula:
log_b(x) = y, if b^y = x

Input:
x = 70
b = 7

Solution:
y = log₇ 70
= log(7 x 2 x 5)
= log₇(7) + log₇(2) + log₇(5)
= 1 + 0.3562 + 0.8271
= 2.1833
log₇(70) = 2.1833
