simplify sqrt(25y^2-9y^2)

Solution

simplify

25 y^{2} - 9 y^{2}

Solution

4 y

Solution steps

25 y^{2} - 9 y^{2}

Add similar elements:

25 y^{2} - 9 y^{2} = 16 y^{2}

= 16 y^{2}

Apply radical rule:

ab = a b,

assuming

a \geq 0, b \geq 0

16 y^{2} = 16 y^{2}

= 16 y^{2}

16 = 4

= 4 y^{2}

Apply radical rule:

a^{2} = a,

assuming

a \geq 0

y^{2} = y

= 4 y
