Question 316583
simplify: sqrt (90) 
a) 30 
b) 3 sqrt (10)
c) 10 srt (3)
d) 9 sqrt (3)

sqrt or square root means you figure out what number times itself equals the number you are finding the square root of

for example the square root of 9 is 3 because 3^2 = 3*3 = 9
the square root of 10 can not be easily done so we leave that sqrt(10)

sqrt(90) = sqrt(9 * 10) = 3sqrt(10)

the answer is b
