Add 19−−√ + 19−−√ .
To simplify the expression, let's assume:
x = sqrt(19)
Therefore, the expression becomes:
x + x
Combining like terms, we have:
2x
Finally, substitute x back:
2 * sqrt(19)
So, the simplified expression is 2sqrt(19).
To add these two numbers, 19√ - 19√, you can combine their terms. Since the terms have the same radical (√), you can add their coefficients. This means you can add 19 + 19, which equals 38. Since the radical part remains the same, you get 38√ as the final answer.
To add the expressions 19√ + 19√, we need to simplify the square roots first. We can use the property of square roots that states √(a + b) = √a + √b.
So, let's simplify the square roots:
√19 + √19
Since both terms under the square root are the same, we can combine them:
2√19
Therefore, the sum of 19√ + 19√ is 2√19.
