5√6 * 7√2 =
16√3 : 2√3 =
64√2 : √8 =
3√7 * 9 =
4√3 (trzeciego stopnia) + 5√125 (trzeciego stopnia) - 2√36 =
-3^4 - (-2)^5 =
x^5 * x^7 : x^2 =

Answer 1

3(x + 7) = 3x + 21
2√3 + 2√16 = 2√3 + 2 * 4 = 2√3 + 8 = 2(√3 + 4)
5√6 * 7√2 = 35√12 = 35 * 2√3 = 70√3
16√3 : 2√3 = 16/2 * √(3/3) =  8 * 1 = 8
64√2 : √8 =  64√2 : 2√2 = 64/2 * √(2/2) = 32 * 1 = 32
3√7 * 9 = 277
4∛3 + 5∛125 - 2√36 = 4∛3 + 5 * 5 - 2 * 6 = 4∛3 + 25 - 12 = 4∛3 + 13
- 3^4 - (- 2)^5 = - 81 - (- 32) = - 81 + 32 = - 49
x^5 * x^7 : x^2 = x^12 : x^2 = x^10
