Sqrt(15)/5 *sqrt(20)

Answers

Answer 1

Answer: so if you mean: $( √(15) )/(5)$ times $√(20)$ then
simplify
rememeber
$x^{ (m)/(n) }= \sqrt[n]{ x^(m) }$
and
$[x^(n)]^(m)= x^(nm)$
and
$√(x) √(y)= √(xy)$

multiply

$( √(15) )/(5)$ times $( √(20) )/(1)$ = $( √(300))/(5)$

simplify √300
√300=√3 times √100
we know that √100=10 so
√300=√3 times 10
therefor
$( √(300) )/(5)$ = $(10√(3))/(5)$ = $(5)/(5)$ times $(2√(3))/(1)$ = 1 times $(2√(3))/(1)$ =2√3

Answer 2

Answer: So,

$( √(15))/(5) * √(20)$

Simplify the square root of 20.
$√(20) = √(4) * √(5) = 2 * √(5) = 2 √(5)$

$( √(15))/(5) * ( 2√(5) )/(1)$

Multiply.
$( 2√(75))/(5)$

Simplify.
$( 2√(25)* √(3) )/(5)$
$( 2 * 5* √(3) )/(5)$
$(10√(3) )/(5)$
$(2√(3) )/(1)$
$2√(3)$
