Can anyone please help me :)
Solnce55 [7]

Answer:

5 to the 15th power.

Step-by-step explanation:

PEMDAS requires us to do parenthesis, then exponents, and then division. Let's do 5³. 5x5x5 is equal to 125. Now, we find 125 to the ninth power. According to my calculations, 125 to the ninth power is equal to 7,450,580,596,923,828,125. Now, we find 5 to the twelfth power, which, according to my calculations, is 244,140,625. Now, we solve. According to my calculations, 7,450,580,596,923,828,125/244,140,625 is equal to 30,517,578,125. 30,517,578,125 is equivalent to 5 to the 15th power. That means that the second option is correct. I hope this helps!

I am simplifying radicals and I've come across one that has me a bit confused.
zhenek [66]

The sqrt of (34 m^4) is  sqrt(34) times sqrt(m^4).

The sqrt of m^4 is easy ... that's just  m^2 .

The other part is more messy.  There's not much you can do with it.

                      sqrt(34) = sqrt(17) times sqrt(2). 

That doesn't help make it any simpler.
You might as well just leave it as sqrt(34). 

Then the final, simplified form of the original expression is

                          m^2 sqrt(34)

How would I solve n/5-3n/10=1/5<br><br>pls help me I am literally failing math.
otez555 [7]

Answer:

53/5

Step-by-step explanation:

since 10 is the denominator of the denominator we can move it to the numerator, giving us 10n/5-3n = 1/5

multiply all sides by 5-3n, giving us 10n = (5-3n)/5

now multiply by 5 to get rid of the final denomintor, 50n = 5-3n

move 3n to the other side 53n = 5, n = 53/5
