�ã49 + �ã343 - �ã2401 =

please help me solve

I can not read your symbols, assume radical for square root

sqrt 49 + sqrt 343 - sqrt 2401 ???
343 = 7^3
2401 = 7^4
so I have
7 + 7 sqrt 7 + 49
= 56 + 7 sqrt 7

forgot the negative

7 + 7 sqrt 7 - 49
- 42 + 7 sqrt 7

To solve the expression �ã49 + �ã343 - �ã2401, we need to calculate each term separately and then combine the results.

First, let's calculate �ã49:
- Since �ã or "�ãroot" denotes the square root, �ã49 means the square root of 49.
- The square root of 49 is 7, as 7 * 7 = 49.

Next, let's calculate �ã343:
- �ã343 means the square root of 343.
- The square root of 343 is 7, as 7 * 7 * 7 = 343.

Lastly, let's calculate �ã2401:
- �ã2401 means the square root of 2401.
- The square root of 2401 is 49, as 49 * 49 = 2401.

Now that we have calculated each term, we can substitute them back into the original expression:
�ã49 + �ã343 - �ã2401 = 7 + 7 - 49

Lastly, we perform the addition and subtraction:
7 + 7 - 49 = 14 - 49 = -35

Therefore, the solution to �ã49 + �ã343 - �ã2401 is -35.
