3^4=81. How do you write as a logarithm

Mathematics
1 answer:
Alla [95]3 years ago
5 0
The form it is currently in is called the exponential form. Which is represented with this equation: 

y = b^x

The equivalent logarithmic equation is: 
x = log_b y

Where b, is a base.
So our power becomes what the problem is equal to, the number that is being brought to that power is the base. The one on the equal sign is what we are taking the log of. So it will look like this:

4 = log_3 81

Please help with areas
Softa [21]

Answer:

Step-by-step explanation:

7) The formula for determining the area of a parallelogram is expressed as

Area = base × height.

Length of base = Area/height

Therefore,

Length of base = 7/2 = 3.5 feet

8) The formula for determining the area of a trapezoid is expressed as

Area = 1/2(a + b)h

Where

a and b are the length of the bases

h is the height. Therefore

21 = 1/2(2 + 4)h

21 = 3h

h = 21/3 = 7 inches

9) Area = base × height.

Height = Area/Length of base

Height = 28/14 = 2 inches

10) a and b are 10 inches each.

Area = 1/2(a + b)h

Therefore,

35 = 1/2(10 + 10)h

35 = 10h

h = 35/10

h = 3 inches
