Use exponential form to evaluate log8(2)

Explanation:

let y =

whenever we transfer base from  log from one side to other it will remain be base after shifting to the other side.

Change log to exponent form

here we have n = y, m=2, x=8    by substituting the values

we will get

         (1)

we can write 8 in power of 2 that is

we will rewrite the above equation (1) as

we can equate the power when base is same then we will get

3y = 1

then

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
