Question

Expand log7 (x^3/y)^3

a.) 9 log7 x + 3 log7 Y
b.) 9 log7 x - 3 log7 Y
c.) 9 log7 x - log7 Y
d.) 3 log7 x - 3 log7 Y

Answer 1

A resposta é a C

Eu com certeza apostaria na c

Answer 2

b.) 9 log7 x - 3 log7 Y

Explanation:

`log_(7)\bigg( \frac{ {x}^(3) }{y} \bigg)^(3) \\ \\ = 3log_(7)\bigg( \frac{ {x}^(3) }{y} \bigg) \\ \\ = 3log_(7) {x}^(3) - 3log_(7)y \\ \\ = 3 * 3log_(7) {x} - 3log_(7)y \\ \\ = 9log_(7) {x} - 3log_(7)y \\ \\`
