333.4 (rounded)

the closest i got to is 11.4

2√25

dont know how to do the last one-

u can try doing this again, the other 2 are right, but last one can be simplified

is it 333?
2000000000000000000

nope, 333 times 333 times 333 probs doesn’t equal 1000

huh. i guess dont really get it with the fractions… :sob:

Oh that’s fine, that’s the part where DoesNotCompute mentioned it:

so the number you see as the denominator (or the last number you see in the fraction) which is in this case 3, means you need the number that you multiply it by itself 3 times which gives you the number required , in this case 125

when you see this: a1/3, it also means: 3a
in this case, a = x * x * x (or x3)

but when you see it this way: √a or this way 2√a or even this way a1/2
it would be, a = x * x (or x2)

so to apply this example 3√125 we should find a number when is cubed gives 125
so let’s try some numbers
3 * 3 * 3 = 9 * 3 = 27
4 * 4 * 4 = 16 * 4 = 64
5 * 5 * 5 = 25 * 5 = 125

so 53 equals to 125

and 3√125 or 1251/3 equals to 5

Oh, okay. so it would be 10 right?

We have been taking functions and system of equations recently, what have y’all been taking?

Some expressions such as 0/0 represent multiple numbers.

median, mode, mean, range

we already learned this but whatever-

We were taking the pythagorean theorem, and that was our project :stuck_out_tongue:

Triangles:

did u know that the divide sign and the % sign means 0/0 as a fraction

I knew the devide sign one but thats cool with the percentage thingy.

as percentages are just fractions turnt into numbers

like 10/100 = 10%

wow, i like this, never noticed it, but it’s quite interesting (talking abt the %)

Knew that one. gets semi-important later on in math.

Someone help. Idk what’s going on here :sob:
I need like a full on explanation rn

Here, they are transforming a binary number to a 10-base number.

10-base number is the counting system we use; essentially starting a new slot every 10 ones.

The formula extracted from the example that does this transformation would be the following

Let d be the digit number from the left
Let n be the 0 or 1

n×2^d-1 + n×2^d-2 + n×2^d-3 … n×2^0

If the binary number has 5 digits, the exponent of the 2 would be 4

Likewise, if it had 7 digits, the exponent of the 2 would be 6

The reason they are multiplying by 2 is because the Binary system is a 2-base system. Meaning every 2 number (aka 0,1) we start a new slot

If you want me to explain with more detail or in a different way, please let me know
