What are the answers ?

Anika [276]

If c = 8 and d = -5:

a) c - 3 = 8 - 3
= 5

b) 15 - c = 15 - 8
= 7

c) 3(c + d) = 3(8 + (-5))
= 3*3
= 9

d) 2c - 4d = 2(8) - 4(-5)
= 16 + 20
= 36

e) d - c^2 = -5 - (8)^2
= -5 - 64
= -69

f) 2d^2 + 5d = 2(-5)^2 + 5(-5)
= 50 - 25
= 25

Which logarithmic equation is equivalent to 3^2 = 9?

noname [10]

Answer: $log_39=2$ is the logarithmic equation which is equivalent to $3^2=9$ .

Step-by-step explanation:

According to the laws of logarithms

$log_b\ x=n$ ,where b=base ,n,x all are positive

It can be written in exponential form such as

$x=b^n$

Now in the given question x=9 ,b=3 and n=2 such that it will equals to

$log_39=2$

Hence the logarithmic equation for $3^2=9$ is $log_39=2$ .
