Question

Which of the following is a like radical to 3x sqrt 5?

Answer 1

we are given

3x sqrt 5

we always do order of operation from left to right

$3x\sqrt{5}$

we can rewrite it as

$3x\sqrt{5}=3 \times x \times \sqrt{5}$

we know that

a*b*c=b*a*c

$3x\sqrt{5}=x \times 3 \times \sqrt{5}$

$3x\sqrt{5}=x (3 \sqrt{5})$..............Answer

Answer 2

$\bf 3x\sqrt{5}\implies 3\cdot x\cdot \sqrt{5}\implies (3)(x)(\sqrt{5})\implies (x)(3)(\sqrt{5})\implies x(3\sqrt{5})$
