Simplify the expression.<br>Write your answer without negative exponents. NEED AN ANSWER ASAP

harina [27]

Answer:

$\boxed{\frac{-3b^4 }{a^6 }}$

Step-by-step explanation:

$\frac{-18a^{-8}b^{-3}}{6a^{-2}b^{-7}}$

$\frac{-18}{6} \times \frac{a^{-8}}{a^{-2}} \times \frac{b^{-3}}{b^{-7}}$

$-3 \times \frac{a^{-8}}{a^{-2}} \times \frac{b^{-3}}{b^{-7}}$

Apply the law of exponents, when dividing exponents with same base, we subtract the exponents.

$-3 \times a^{-8-(-2)} \times b^{-3- (-7)}$

$-3 \times a^{-8+2} \times b^{-3+7}$

$-3 \times a^{-6} \times b^{4}$

${-3a^{-6}b^{4}}$

The answer should be without negative exponents.

$a^{-6}=\frac{1}{a^6 }$

$\frac{-3b^4 }{a^6 }$

One pound of ground beef costs $3.99. Five pounds of ground beef costs $17.45. How much cheaper is the ground beef per pound if

xxTIMURxx [149]

Step-by-step explanation:

Ok, so, to find this, remember- to find the true price of an item, remember the equation (PRICE DIVIDED BY QUANTITY), this will give you true price. So, for the individual, its $3.99 for one pound. In bulk, to find the true price, do price divided by quantity. $17.45/5= 3.45. So thats the better deal. Anyways, to find out how much cheaper it is, subtract 3.45 from 3.99. The answer is .54, however, since you need to round to the nearest tenth place, the answer would be .50

Out Of 100 what numbers are prime and composite

Tamiku [17]

The answers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and 97.

All of these number CANNOT be divided by any number (or cannot have any smaller numbers multiplied together to make it) besides 1 and itself (1 * 5 = 5).
