" $\frac{8b^4}{3a^1^2}$ " .

__________________________________________________

Step-by-step explanation:

__________________________________________________

We are asked to simplify the following given expression:

________________

$\frac{(\frac{2b^3c}{a^3b^2c^2})^4}{6}$ ;

________________

Let us start with the "numerator" ; which functions as a separate "fraction"—in and of itself—with its own numerator and denominator:

________________

$(\frac{2b^3c}{a^3b^2c^2})^4$ ;

________________

Note the following "division" property of exponents:

________________

→ $(\frac{a}{b})^c = \frac{a^c}{b^c}$ ; $b\neq 0$ .

________________

Then:

→ (\frac{2b^3c}{a^3b^2c^2})^4 ;

________________

= $\frac{(2b^3c)^4}{(a^3b^2c^2)^4}$ ; $a\neq 0$ ; $b\neq 0$ ; $c\neq 0$ .

________________

Then, start by simplifying "this particular numerator":

→ (2b^3c)^4 = ? ;

Note the following "multiplication" property of exponents:

→ (a^b)^c = a^(^b^*^c^) ; $b\neq 0$ .

________________

Then:

→ (2b^3c)^4 = 2^4 * b^(^3^*^4^)(c^4) = (2*2*2*2) * b^1^2 * c^4 = 16 b^1^2c^4 ;

________________

The continue by simplifying "this particular denominator":

________________

→ (a^3b^2c^2)^4 = a^(^3^*^4^)b^(^2^*^4^)c^(^2^*^4^) = a^1^2b^8c^8

________________

And we have:

________________

→ $\frac{16b^1^2c^4}{a^1^2b^8c^8}$ .

________________

Note the following properties of exponents:

________________

→ $a^-^b = \frac{1}{a^b}$ ; $a\neq 0$ .

________________

→ $\frac{a^c}{a^b} = a^(^c^-^b^)$ ; $a \neq 0$ .

________________

So, we have:

→ \frac{16b^1^2c^4}{a^1^2b^8c^8} ;

________________

→ 16 ÷ 1 = 16 ; ("1" is the "implied coefficient") ; in the numerator.

→ a^1^2 ; stays in the denominator;

→ $\frac{b^1^2}{b^8} = b^(^1^2^-^8^)=b^4$ ; replaces the original: " b^1^2 " [in the numerator]; b^8 is eliminated in the denominator;

→ $\frac{c^4}{c^8} = c^(^4^-^8^) = c^-^4 = \frac{1}{c^4}$ ; The original " c^4 " [in the numerator] is eliminated; the original " c^8 " [in the denominator] is replaced with " c^4 " . ________________

And the expression is rewritten as:

________________

→ $\frac{16b^4}{a^1^2c^4}$ ;

________________

→ Now, from the original given problem, we divide this value by "6" ;

which is the same value we get by multiplying this value by: " $\frac{1}{6}$ " ;

→ as follows:

________________

→ $\frac{16b^4}{a^1^2c^4} *\frac{1}{6}$ ;

________________

Considering the "16" and the "6" ; each of these can be divided by "2" ;

Specifically, " (16 ÷2 = 8) " ; and: " (6 ÷ 2 = 3) " .

________________

So, we can rewrite the expression — by substituting "8" in lieu of the "16" ; and "3" in lieu of the "6" ; as follows:

________________

→ $\frac{8b^4}{a^1^2} * \frac{1}{3}$ ;

And further simplify;

→ $\frac{8b^4}{a^1^2} * \frac{1}{3} = \frac{(8b^4 * 1)}{(a^1^2*3)} = \frac{8b^4}{3a^1^2} .$

Hope this helps!

Best wishes!

Answer from: Quest

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

$\frac{48}{4}$ = 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
