That's how people write "raised to the power of" on this website.

7^2 means '7 squared'.

4^6 means '4 raised to the sixth power'.

(a+b+D)^3 means (a+b+D)-cubed.

This website does have a way to write actual exponents, but when you
use them, they're so tiny that you can't read them clearly, and it's easy
to mistake one exponent for a different one. Just one of the many, many,
. . . . . . . . . . . . . many, . . . . . . . . . . . . . . . little
problems with this website.

Select the number like that matches the expression |-6-(-3)|

Harman [31]

Answer:

Step-by-step explanation:

Firstly, do the numbers inside the absolute value bars.

-6-(-3)

The two negatives that are together turn to a addition sign.

-6+3

You can just subtract 6 and 3 which is 3 and add the - to it.

|-3|

The -3 turns to a 3 since the absolute value bars make all numbers positive within the bars.

Hope this helped.

at one scholl at prep level there were 5 set of twins,two sets of triplets and one set of quadruplets starting school this year.

IrinaK [193]

Answer: The fraction of set of twins= $\frac{5}{8}$

The fraction of sets of triplets= $\frac{2}{8}$

The fraction of set of quadruplets= $\frac{1}{8}$

Step-by-step explanation:

Given: The number of set of twins=5

The number sets of triplets = 2

The number of set of quadruplets=1

⇒ The total number of multiple birth students =5+2+1=8

∴ The fraction of set of twins= $\frac{\text{set of twins}}{\text{ total multiple birth students}}=\frac{5}{8}$

∴ The fraction of sets of triplets= $\frac{\text{set of triplets}}{\text{ total multiple birth students}}=\frac{2}{8}$

∴ The fraction of set of quadruplets= $\frac{\text{set of quadruplets}}{\text{ total multiple birth students}}=\frac{1}{8}$

Which of the following is equivalent to the expression below sqrt 8 - sqrt 72 + sqrt 50

mash [69]

Answer:

Step-by-step explanation:

$\sqrt{8}-\sqrt{72}+\sqrt{50}$ These cannot combine the way they are. The rule for adding and subtracting radicals is really picky. Not only does the index have to be the same (the little number that is sitting outside in the bend of the radical {ours is a 2, which isn't usually there, but is instead understood to be a square root}), but the radicand, the expression under the square root (or cubed root, or fourth root, etc) has to the same as well. All of our radicals are square roots, so that's good, but the radicands are all different. The first one is an 8, the next one is a 72, and the last one is a 50. BUT if we can rewrite them by simplifying them and then the radicands are the same, we're in good shape.
