[From: ] [author: ] [Date: 11-05-20] [Hit: ]
you know i am already pretty down, i cant fail at this also D:so please does anyone know any calculators that : simplify radical expressions, like ( square root of 4x^4 , Square root of 300),the perfect squares are 1,4,......
well you see i am not going to lie, theres this big take home test and i COMPLETELY forgot with all my health issues going around, ( recently found out i was a diabetic ) and well this would just make it so much worse , you know i am already pretty down, i cant fail at this also D: so please does anyone know any calculators that : simplify radical expressions, like ( square root of 4x^4 , Square root of 300),

When dealing with square roots remember this:

√a * √a = a
√a^2 = a
√a^3 = √a * √a * √a = a * √a = a√a
√(a * b) = √a * √b

√(4x^4)
=
√4 * √x^4
√4 * √x * √x * √x * √x
2 * √x * √x * √x * √x
2 * x * x
= 2x^2

√300
find factors that are a perfect square

the perfect squares are 1,4,9,16,25,49,64,100,121 etc

100 * 3 is equal to 300
so √300
=
√100 * √3
since √100 is 10
the answer is
10√3

-
√4x^4
= 2x² {square root of 4 is 2 and square root of x^4 is x²

√300
= √100 √3 {broke 300 into two factors, one which has a perfect square root}
= 10√3 {square root of 100 is 10}

yes..it is called your brain.

√(4x^4) = √4 * √x^4 = 2 * x^2 = 2x^2

√300 = √100 * √3 = 10 * √3 = 10√3
