If logM/N=5 and logP/N=7, what can you say about the relationship between M and P?. . A. M=2P. B. P=2M. C. P=100M. D. P=10M
liubo4ka [24]
<span>log (M/N) = log M - log N
 so log M - log N = 5
log (P/N) = log P - log N
so log P - log N = 7
 If you subtract equation 2 from equation 1, you have log M - log P = -2
 That means that log (M/P) = -2 ----> 10^-2 = M/P ---> P = 100M</span>

If 3x−y=12, what is the value of 8x2y?
ArbitrLikvidat [17]

One approach is to express

8x2y

so that the numerator and denominator are expressed with the same base. Since 2 and 8 are both powers of 2, substituting 23 for 8 in the numerator of 8x2y gives

(23)x2y

which can be rewritten

23x2y

Since the numerator and denominator of have a common base, this expression can be rewritten as 2(3x−y). In the question, it states that 3x−y=12, so one can substitute 12 for the exponent, 3x−y, which means that

8x2y=212

The final answer is A.
