In this question , we have to remeber the rule of combining two negative numbers . And the rule is, when combining two negative terms, we have to add them with negative sign .For e.g.-2-15=-(2+15)=17. SImilarly, -3 -14 =-(3+14)=-17. And none of them got -17. Dominique got 11 and Juan got 17. So none of them is correct .

Juan is correct because if you put -3-14 it’s equal to -17 so Juan is right.

Use the following steps to prove that log b(xy)- log bx+ log by.

borishaifa [10]

Answer with Step-by-step explanation:

a. $x=b^p$

$y=b^q$

Taking both sides log

$log x=plog b$

Using identity: $logx^y=ylogx$

$p=\frac{logx}{log b}=log_b x$

Using identity: $log_x y=\frac{log y}{log x}$

$log y=qlog b$

$q=\frac{log y}{log b}=log_b y$

b. $xy=b^pb^q$

We know that

$x^a\cdot x^b=x^{a+b}$

Using identity

$xy=b^{p+q}$

c. $log_b(xy)=log_b(b^{p+q})$

$log_b(xy)=(p+q)log_b b$

Substitute the values then we get

$log_b(xy)=(log_b x+log_b y)$

By using $log_b b=1$

Hence, $log_b(xy)=log_b x+log_b y$

15 cookies burned because if you Turn $\frac{3}{4}$ into a decimal then multiply it by 20 you get 15 and thats your answer.
