X=7^y how can you rewrite this equation in y = form ?
Anuta_ua [19.1K]

Answer:

y = lnx / ln 7.

Step-by-step explanation:

x = 7^y

Take logarithms of both sides:

ln x = ln 7^y

ln x = y ln 7     ( because ln a^b = b ln a.   One of the Laws of Logarithms).

y = lnx / ln 7.

Evgesh-ka [11]

Answer:

\frac{5}{192}

Step-by-step explanation:

\frac{3}{8} * \frac{2}{6} * \frac{4}{8} * \frac{5}{12}

Multiply all numerators

3 * 2 * 4 * 5 = 6 * 20 = 120

Multiply all denominators

8 * 6 * 8 * 12 = 48 * 96 = 4,608

\frac{120}{4608}

Simplify

\frac{5}{192}

Hope this helps :)
