Simplify this answer <br><br> please help!

Answer:

(hope this helps can I pls have brainlist (crown) ☺️)

Step-by-step explanation:

7^8 x 7^3 x 7^4 / 7^9 7^5

= 7^(8+3+4) / 7^(9+5)

= 7^15 / 7^14

= 7^(15-14)

= 7.

When the bases of the numbers are the same when multiplying numbers with exponents, you can just add the exponents like so:

7^8 x 7^3 x 7^4= 7^15

Now, look at the rest of the simplified equation and do the same to the denominator:

 7^15 / 7^9 x 7^5 ⇒ 7^15/ 7^14

When the bases are the same in the fraction, you are allowed to subtract the exponents. This will lead you to the simplified answer  = 7^15-14 = 7^1  = 7

Michael Jordan is 6'6'' tall and could jump 4 feet of vertical distance off the ground.A basketball net's rim is 3.9 meters off
Vaselesa [24]
No. 6+4=10. Michael Jordan's head reaches 10'6" above the ground. A meter is slightly more than 3 feet, so 3.9 meters is more than 11'8". 

MJ's head would not reach the rim by more than a foot.

Mr.Smith waters one of his plants every 10 days and another plant every 14 days. If he waters both plants today, when is the nex
Allushta [10]

Answer:

After 140 days

Step-by-step explanation:

The next time both plants will be watered together is simply the LCM of 10 and 14.

10 has multiples: 10, 20, 30, 40 , 50 ....

14 has multiples: 14, 28, 42, 56 ....

When will they next be equal?? That's the LCM.

We first do prime factorization of the numbers and then multiply each factor the greatest number of times it occurs in either number.

<u>Prime Factorization</u>

10 = 2 * 5

14 = 2 * 7

So,

LCM = 2^2 * 5 * 7 = 140

After 140 days
