Write how many hundred thousands, ten thousands, and thousands there are in the numbers of acres of Land Big Bend National Park
sveta [45]

To solve this problem, we must remember our place values. 100,000 represents hundred thousands, 10,000 represents ten thousands, and 1,000 represents thousands similarly to how 100 represents hundreds, 10 represents tens, and 1 represents ones. Using this knowledge, we know that the number 8 is in the hundred thousands place, the number 0 is in the ten thousands place, and the number 1 is in the thousands place.

This means that there are 8 hundred thousands, 0 ten thousands, and 1 thousand in the number of acres of land the National Park owns.

Hope this helps!

HELP! SIMPLIFY!
Vitek1552 [10]
1)  (m³n⁵)(mn⁴)
     -----------------
      m⁻³n²

Simplify.

m⁴n⁹
-------
m⁻³n²

When the bottom power is a negative, you add it to the power on top, & when the power is a positive, you subtract it.

m⁴ + m³ = m⁷

n⁹ - n² = n⁷

So, our answer for #1 is m⁷n⁷

2)  6a²b³
     ---------
        4a

Please read rules in #1.

6 / 4 = 3/2 & a² - a = a

So, our answer is 3a
                               -----
                                 2

3)  5⁶a⁶b³
     ---------
       5²ab³
5⁶ - 5² = 5⁴ AND a⁶ - a = a⁵ AND b³-b³ = 0

So, our answer is 5⁴a⁵

Simplify 5⁴

5 × 5 × 5 × 5 = 625

So, our final answer is :

625a⁵
