^3 sqrt x^27
Simplify assuming the variable represents a positive number
Simplify assuming the variable represents a positive number
The cubed root of x^27 can be simplified as follows:
(x^27)^(1/3)
Since the exponent outside of the parentheses is being applied to each term inside, you can divide the exponent by 3:
x^(27/3)
Simplifying the exponent further:
x^9
So the simplified expression is x^9.
(x^27)^(1/3)
Since the exponent outside of the parentheses is being applied to each term inside, you can divide the exponent by 3:
x^(27/3)
Simplifying the exponent further:
x^9
So the simplified expression is x^9.
1/3 + 3/10
To add the fractions 1/3 and 3/10, you need to find a common denominator.
The common denominator in this case is 30 because it is divisible by both 3 and 10.
To convert 1/3 to a fraction with a denominator of 30, you multiply the numerator and denominator by 10: (1/3) x (10/10) = 10/30.
To convert 3/10 to a fraction with a denominator of 30, you multiply the numerator and denominator by 3: (3/10) x (3/3) = 9/30.
Now you can add the two fractions together: 10/30 + 9/30 = 19/30.
So 1/3 + 3/10 equals 19/30.
The common denominator in this case is 30 because it is divisible by both 3 and 10.
To convert 1/3 to a fraction with a denominator of 30, you multiply the numerator and denominator by 10: (1/3) x (10/10) = 10/30.
To convert 3/10 to a fraction with a denominator of 30, you multiply the numerator and denominator by 3: (3/10) x (3/3) = 9/30.
Now you can add the two fractions together: 10/30 + 9/30 = 19/30.
So 1/3 + 3/10 equals 19/30.
Factor 2x^6+18x^4
To factor the expression 2x^6 + 18x^4, we can factor out the greatest common factor. In this case, the GCF is 2x^4.
So, we can rewrite the expression as the product of the GCF and the remaining terms:
2x^4(x^2 + 9)
Therefore, the factored form of 2x^6 + 18x^4 is 2x^4(x^2 + 9).
So, we can rewrite the expression as the product of the GCF and the remaining terms:
2x^4(x^2 + 9)
Therefore, the factored form of 2x^6 + 18x^4 is 2x^4(x^2 + 9).
Find the determinant
|5 7|
|4 3|
|5 7|
|4 3|
To find the determinant of a 2x2 matrix, you use the formula:
determinant = (a*d) - (b*c)
In this case, the matrix is:
|5 7|
|4 3|
Using the formula, the determinant is:
(5*3) - (7*4) = 15 - 28 = -13
So, the determinant of the given matrix is -13.
determinant = (a*d) - (b*c)
In this case, the matrix is:
|5 7|
|4 3|
Using the formula, the determinant is:
(5*3) - (7*4) = 15 - 28 = -13
So, the determinant of the given matrix is -13.
1 1/6×9
To calculate 1 1/6 multiplied by 9, we need to convert the mixed number 1 1/6 to an improper fraction first.
1 1/6 is equal to 7/6 as an improper fraction.
Now we can multiply the improper fraction by 9:
7/6 * 9 = (7 * 9) / 6 = 63/6
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 3:
(63/3) / (6/3) = 21/2
Therefore, 1 1/6 multiplied by 9 equals 21/2.
1 1/6 is equal to 7/6 as an improper fraction.
Now we can multiply the improper fraction by 9:
7/6 * 9 = (7 * 9) / 6 = 63/6
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 3:
(63/3) / (6/3) = 21/2
Therefore, 1 1/6 multiplied by 9 equals 21/2.
