What is the value of a when we rewrite 8^x as a^-x/9

Andre45 [30]

Answer:

$a = \frac{1}{134217728}$

Step-by-step explanation:

Given

$8^x = a^{-x/9}$

Required

Find a

Take log of both sides

$log(8^x) = log(a^{-x/9})$

Apply law of logarithm

$x\ log(8) = (-x/9) log(a)$

Divide both sides by a

$log(8) = -\frac{1}{9} log(a)$

Multiply both sides by -9

$-9\ log(8) = log(a)$

Apply law of logarithm

$log(8^{-9}) = log(a)$

Cancel out log

$8^{-9} = a$

Rewrite as:

$a = 8^{-9}$

Apply law of indices

$a = \frac{1}{8^9}$

$a = \frac{1}{134217728}$

The ratio of boys to girls in a class is 3:4. There are 35 students in the class. How many more girls than boys are there?

lisov135 [29]

Answer:

Step-by-step explanation:

sum the parts of the ratio, 3 + 4 = 7 parts

Divide the number of students by 7 to find the value of one part of the ratio

35 ÷ 7 = 5 ← value of 1 part of the ratio, then

3 parts 3 × 5 = 15 ← number of boys

4 parts = 4 × 5 = 20 ← number of girls

20 - 15 = 5

There are 5 more girls than boys
