СРОЧНО ПЛИЗЗЗ!!Корень из 15 * корень из 135 - корень 2 * корень 242
√15*√135-√2*√242=√15*35-√2*242=√2025-√484=45-22=23
√15 * √135 - √2 * √242 = √(5*3) * √(5*27) - √2 * √(2*121) =
= √ 5*√3 * √5*√27 - √2 * √ 2*√121 = 5 √3 *√(3*9) - 2*11 =
= 5 √3 *√ 3*√ 9 - 22 = 5* 3*√ 9 - 22 = 5* 3*3 - 22 = 45 -22 = 23
