Answer:

b.) 9 log7 x - 3 log7 Y

Step-by-step explanation:

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

What is the value of e^ln7 x1<br> 7e<br> 7x<br> 7

sweet-ann [11.9K]

Answer:

Both answer shown

IF it is

$e^{ln 7x}= 7x$

IF it is

$e^{ln 7}\times 1}=7$

Step-by-step explanation:

Given: Little confusion is in the question

e^ln7 x1

i.e $e^{ln 7x}$

To Find:

$e^{ln 7x}= ?$

Solution:

We know Logarithmic identity as

$\ln e = 1$

$\ln e^{x} = x$

Similarly,

$e^{\ln x}=x$

IF it is

$e^{ln 7x}= 7x$

IF it is

$e^{ln 7}\times 1}=7\times 1=7$

What is the quotient of a^3b/c^2 / 2ab/c^3 ? Assume a0, b0, and c0. a2c a3bc

kolbaska11 [484]

Answer:

(-6a^3b + 2ab^2)(5a^2 - 2ab^2 - b)

Multiply each term in the first parenthesis by each term in the second parenthesis.

Then combine like terms.

-30a^5b +12a^4b^3 +6a^3b^2 +10a^3b^2 -4a^2b^4 -2ab^3

-30a^5b + 12a^4b^3 +16a^3b^2 - 4a^2b^4 - 2ab^3
