Write the log equation as an exponential equation. You do not need to solve for x. \log_9\left(2\right)=2x-1 log 9 (2)=2x−1

monitta

Answer:

$9^{2x-1} = 2\\$

Step-by-step explanation:

According to the law of logarithm;

$If \ log_ab = x\\a^x = b$

Given

$\log_9\left(2\right)=2x-1$

Comparing with the original expression;

a = 9, b = 2 and c = 2x - 1

Substitute into the result indicinal expression;

$9^{2x-1} = 2\\$

This gives the required exponential equation

Blake has b baseball cards. His aunt gave him more cards, increasing his total number of cards by 25%. Which expression represen

Naily [24]

Answer:

Blake's total number of cards now: 1.25b

Step-by-step explanation:

Total number of cards now would be equal to 25% increase from b.

This means we INCREASE b by 25% OF b.

What is 25% of b???

$\frac{25}{100}*b\\=0.25b$

Now we need to ADD this to original amount, b.

So, $b+0.25b=1.25b$

HELP! Write the logarithmic equation in exponential form!

Schach [20]

Answer:

We conclude the exponential form will be:

$729\:=\:\:9^3\:$

Step-by-step explanation:

Given the logarithmic equation

$3=\log _9\left(729\right)$

Writing the logarithmic equation in exponential form.

We know that

$\:\log _a\left(b\right)=x\:$ → $\:\:a^x=b$

Let us write the logarithmic equation in exponential form using the expression above

a = 9

b = 729

x = 3

Thus, we conclude the exponential form will be:

$729\:=\:\:9^3\:$

Is the prime factorization below correct? 24 24+2.3.4 O Correct Incorrect

xenn [34]

Is the prime factorization below correct

24
24+2.3.4

Answer: 100

Prime numbers are natural numbers (positive whole numbers that sometimes include 0 in certain definitions) that are greater than 1, that cannot be formed by multiplying two smaller numbers. An example of a prime number is 7, since it can only be formed by multiplying the numbers 1 and 7. Other examples include 2, 3, 5, 11, etc.

There are 4 king cards:

King of Hearts

King of Diamonds

King of Clover

King of Spades

This is 4 cards in a standard deck of 52. Set as a fraction 4/52.

Simplify:

(4/52)/(4/4) = 1/13

1/13 is the probability of drawing a KIng card.
