The square root of 100 = 10 The square root of 225 = 15 The sum = 10 + 15 = 25

No. The Square root of x is not the value of x. So it can not be simplified beyond: Root X + root 3x Yes. The square root of 3x equals the square root of 3 times the square root of x, so when you add another square root of x, you can factor out the square root of x, thereby simplifying the expression to the square root of x times the sum of one plus the square root of three.

Square root of 2 = 1.414213562... Square root of 7 = 2.645751311... The sum is 4.059964873...

the answer is actually 29 because ask your teacher he'll ive you the work <3 Answer: PEMDAS-order of operations The square root of 100 is 10. The square root of 225 is 15. The sum of 10 + 15 is 25. The product of 6 and 25 is 250.

because ur supposed to do it thAt way buddy

Assuming the roots are positive, then ~ 15.59.

No. The right hand side is always greater - unless both components are zero.

sqrt(15) + sqrt(25) = 5 + sqrt(15) = 8.873 (using principal roots only).

The sum of a [single] square equals the square.

No. The Square root of x is not the value of x. So it can not be simplified beyond: Root X + root 3x Yes. The square root of 3x equals the square root of 3 times the square root of x, so when you add another square root of x, you can factor out the square root of x, thereby simplifying the expression to the square root of x times the sum of one plus the square root of three.

You can. Just add the numbers together, and find their square root. One plus three is four; the square root of the sum is two.

If you have a data set, simply take the square root of the sum of the squares of the data points. Let's say you have three numbers a, b, and c. RSS = SQRT(a2 + b2 + c2).

81 -- 8+1 = 9 -- square root of 81 = 9
