 \sqrt{8 \times 30}  \times  \sqrt{60}  =  \sqrt{8 \times 30 \times 60}  =  \sqrt{2 \times 2 \times 2 \times 3 \times 10 \times 10 \times 2 \times 3}  = 2 \times 2  \times 3 \times 10 = 12 \times 10 = 120

Every April, the city of Almaty holds a marathon. It started as a small event in 2012, with around 2,500 runners, but in 2015 the number increased to 19,000. People come from many countries to take part. There are runners from Russia, Kyrgyzstan, the UK, the USA, Italy, Spain, Denmark and Norway, but most people come from Almaty and other parts of Kazakhstan. The organizers started the marathon to promote healthier lifestyles. Everyone knows exercise is good for you, but sometimes it is difficult to find the time to do sport. But people like challenges, and a marathon gives them something to aim for. It's impossible to do nothing all year then run 42 km. You have to train and increase the distance you run over a number of months. Apart from the marathon, there are other shorter events in the year to keep people interested in running. Anyone living in Almaty can enter the marathon, so families and friends can enter together and this helps people feel part of the city. The event also raises money for disabled children to do sport and gives them a better life. a Over 20,000 people enter and watch the marathon, so the organizers need lots of volunteers to give each runner food and drink and show them where to go. Anyone can volunteer; you don't need to be from Almaty or good at running to do this, but you do need a lot of energy, and it is better to do something for your community than not do anything.помогите укаратите,сам не знаю как укаратить мне надо на море рассказать, ПОМОГИТЕ ПОЖАЛУЙСТА ДАМ СТОЛЬКО БАЛЛОВ СКОЛЬКО СМОГУ​
