Don't know what x is and if it's radical must be in simplest form

Hi i’m back at my moms now i’ll call her when she can get there i’m gonna go first

Just add 10+3m the m means the roman numeral m is often used to indicate one thousand, and mm is used to indicate one million. for example, an expense of $60,000 might appear as $60m. sales of $3,000,000 might be written as $3mm. internet advertisers are familiar with cpm which is the cost per thousand impressions. so 10+3m= 300,000,010hope this and if it does can i have brainlest? if not tell me what i did wrong but i’m pretty sure i am right.
