Loga n=z  ⇔a^z=n

Therefore:
3)log 1/4  1=0    ⇔(1/4)⁰=1
4)log 1/2  32 -5  ⇔(1/2)⁻⁵=2⁵=32

6)
log 27  3=n  ⇔ 27^n=3 
27=3³
(3³)^n=3  ⇒n=1/3    (3³)¹/³=3³/³=3¹=3

Answer: log 27  3=1/3

7)
log1/4 256=n  ⇔(1/4)^n=256
256=2⁸=4⁴
(1/4)^n=4⁴  ⇒n=-4       [ (1/4)⁻⁴=4⁴=256  ]

Answer: log1/4 256=-4

9)
log 10  0.001=n  ⇔  10^n=0.001
0.001=10⁻³
10^n=10⁻³  ⇒n=-3

answer: log 10    0.001=-3

10)
log 64  2=n  ⇔64^n=2
64=2⁶
(2⁶)^n=2    ⇒2(⁶n)=2¹ ⇒  6n=1  ⇒  n=1/6

answer: log 64    2= 1/6

nataly862011 [7]

Answer:

Approximately 6 buses

Step-by-step explanation:

If you are wanting know how many vans they are going to need:

26 + 32                    -This helps you know how many total kids there are

= 58

58 / 10                      -This solves how many buses you'll need

= 5.8                   - Round up, and say you need 6 buses.

A bag contains 31 checkers—13 red and 18 black. Determine whether the events "a red checker is selected, not replaced and then a
Ipatiy [6.2K]

Answer:

dependent, 39/155

Step-by-step explanation:

Since the checkers are not replaced, the events are dependent since the number of checkers in the bag  when you pick the second time depends on the first pick.

31 checkers—13 red and 18 black.

P(red) = red/ total

          = 13/31

Keep the checker

Then 30 checkers—12 red and 18 black.

P(black) = black/ total

          = 18/30 = 3/5

P ( red, keep,black) = 13/31 *3/5

                                   39/155
