Given logbM=3.2 logbN=-1.5 and logbP=2.4 find the value of logb(m^2N/p)

artcher [175]

The formulas:
$\log_a (xy)=\log_a x + \log_a y \\
\log_a (\frac{x}{y})=\log_a x - \log_a y \\
\log_a (x^n)n \log_a x$

Expand the expression:
$\log_b (\frac{m^2n}{p})=\log_b m^2 + \log_b n - \log_b p= 2 \log_b m+\log_b n - \log_b p$

Plug the values into the expression:
$\log_b m=3.2 \\ \log_b n=-1.5 \\ \log_b p=2.4 \\ \\
2 \log_b m+\log_b n - \log_b p=2 \times 3.2-1.5-2.4=6.4-3.9=2.5 \\ \\
\boxed{\log_b (\frac{m^2n}{p})=2.5}$

Paladinen [302]

Take out the factor of 3 from both numbers

(69)/3 = 23

(12)/3 = 4

69 + 12 can be rewritten as 3(23 + 4)

What is the ratio of pennies to dimes in a daller

cluponka [151]

we know that 100 pennies = 1 dollar and, 10 dimes = 1 dollar so the ratio would be;

100:10 or 100/10

and in simplest form: 100:10 = 10:1 and 100/10 = 10

HELP PLEASE 10 POINTS!!!

7nadin3 [17]

Answer:

First, write 80% as 80100. Then write an equivalent ratio that has the answer in the numerator and 200 in the denominator. 100 x 2 is 200, so 80 x 2 will be the answer. 80 x 2 = 160. The answer is $160.
