Hi!
Square roots where the things under the root are multiplied (for example ) can be split up into .
That's what I'm going to do in this case. I'm going to split into
Now, the cube root of 125 is 5, because 5 * 5 * 5 = 125, and that is the definition of a cube root. (What multiplied 3 times by itself is equal to what's under the root)
Now to look at what the cube root of is.
A cube root can be rewritten as , same as a square root can be rewritten to .
So if you take the cube root of x^12, you can change it to:
If you have a case like this, then you can multiply the two powers (in this case 12 and 1/3) to simplify it. 12 * 1/3 = 4, so you get x^4.
Now putting the two together, you get:
5 as your answer.
Hope this helped!
Answer: I don’t know
Step-by-step explanation: I don’t know because there is no numbers but the coldest Celsius I know is -273 degrees Celsius
Answer:
The smaller number: a = 10
The larger number is 32
Step-by-step explanation:
a - the smaller number
2a - twice the smaller number
2a+12 - twelve more than the twice smaller number (the larger number)
a + 2a+12 - the sum of the numbers
a + 2a+12 = 42
-12 -12
3a = 30
÷3 ÷3
a = 10
2a+12 = 2×10+12 = 20+12 = 32
Check: 10+32=42
Answer:
to change a mixed number into an improper fraction, you just need to take the whole number in the problem and multiply it by the denominator and add it to the numerator.
To change an improper fraction into a mixed number you divide the numerator by the denominator and put the whole number you get in front of the left over fraction.
