Olin [163]

$\frac{5}{6} \times 1 \frac{2}{3} \\ \\ = \frac{5}{6} \times \frac{1 \times 3 + 2}{3} \\ \\ = \frac{5}{6} \times \frac{5}{3} \\ \\ = \frac{25}{18}$

The correct answer is 25/18.

4 3/2 solve in indices

mylen [45]

Answer:

(2^2)^3/2 = (2)^3 = 8

Step-by-step explanation:

So to solve (4)^3/2 ,you have to realise that you need to remove the denominator in the exponent value which in this case is 2

In order to remove the 2,you would need a 2 in the numerator of the exponent .While understanding all this the value 4 can be equated as 2^2.

Thus your means of getting a 2 in the numerator is solved by simply replacing the 4 with 2^2

Thus what you will get is (2^2)^3/2

Now we have a property in exponent where

(x^m)^n = (x)^mn

Thus (2^2)^3/2 = (2)^3 =8

What is the solution to log Subscript 2 Baseline (9 x) minus log Subscript 2 Baseline 3 = 3

sdas [7]

The value of x is $\frac{8}{3}$

Explanation:

The expression is $\log _{2}(9 x)-\log _{2}(3)=3$

Adding $\log _{2}(3)$ to both sides of the equation, we get,

$\log _{2}(9 x)=3+\log _{2}(3)$

Using log definition, if $\log _{a}(b)=c$ then $b=a^{c}$ , we have,

$9 x=2^{3+\log _{2}(3)}$

Using exponent rule, $a^{b+c}=a^{b} a^{c}$ ,

$9x=2^{\log _{2}(3)} \cdot 2^{3}$

Simplifying, we have,

$9x=3\cdot8\\9x=24$

Dividing both sides by 9, we have,

$x=\frac{24}{9}$

Simplifying,

$x=\frac{8}{3}$

Thus, the value of x is $\frac{8}{3}$
