Multiply the entire expression by a least common multiple and then simplify the expression. In this case, the least common multiple is 30 so multiply the entire expression by 30 and simplify.

How do you solve this equation x2 equals 49 using the square root property?
if x^2 = 49, then the square root property says you can take the square root of both sides as long as you make one a plus-minus. x^2 = 49, which means square root of x^2 = plus minus the square root of 49 the square root of 49 is 7, so +- 7. We get: x = plus/minus 7 (this means either positive 7 or negative 7)

What is the square root of - 0.50?
there is no real square root of a minus number (think about it, minus x minus = plus, plus x plus=plus, and you can't have a minus x plus if it's a square root). However, there is an imaginary root which is "1/2i", where "i" represents the square root of -1. This number doesn't actually "exist" as such, it is just a theory which makes doing maths easier. However if you're not familiar with the concept of "i", you're probably not meant to end up with a minus square root (anything below A level further maths you don't usually need "i") . Check your calculations again.
