Plz answer its easy math.

Serga [27]

<h2>Greetings!</h2>

Answer:

B and E

Step-by-step explanation:

The rules of indicies states:

$x^{a}$ ÷ $x^{b}$ = $x^{a-b}$

So $3^{-8}$ ÷ $3^{-4}$ = $3^{-8 - - 4}$ = $3^{-4}$

So that means B is one of the correct answers.

To find the other correct value, you can divide the two fractions as stated in the question:

$3^{-8}$ by $3^{-4}$ = $\frac{1}{81}$

81 is equivalent to 3⁴

So that means E is also correct.

prohojiy [21]

Answer:

Step-by-step explanation:

Sum the parts of the ratio, 5 + 9 + 13 = 27 parts

Divide the amount of concrete by 27 to find the value of one part of the ratio.

324 ÷ 27 = 12 ← value of 1 part of the ratio , thus

5 parts = 5 × 12 = 60 ← cement

9 parts = 9 × 12 = 108 ← sand

13 parts = 13 × 12 = 156 ← gravel
