Number 2 says Write the given equation in exponential form. Log8 1/512=-3

MA_775_DIABLO [31]

In exponential form it is given as, 8⁻³ = $$\frac{1}{512}$

Step-by-step explanation:

We have to write the given equation in the exponential form, that is in the form of base to the power value.

Given:

log₈ ( $$\frac{1}{512}$ ) = -3

Here the base is 8.

In the exponential form, it is written as,

base to the power 3 = 512

Here the reciprocal of 512 is given, so,

base to the power -3 = $$\frac{1}{512}$

So the exponential form is given as, 8⁻³ = $$\frac{1}{512}$

You have a 1 in 4 chance of winning a game. How would you calculate the probability that you will win 3 times in a row?

Ierofanga [76]

Answer:

The probability of winning three games in a row is 1/64 or 1.6%

Step-by-step explanation:

Probability of winning a game = 1/4

Probability of winning two games in a row = 1/4 * 1/4 = 1/16

Probability of winning three games in a row = 1/4 * 1/4 * 1/4 = 1/64

Probability of winning three games in a row = (1/4)³ = 1/64

1/64 = 0.015625

1/64 = 1.6% (rounding to the next tenth)
