Answer:

#=2a^3bsqrt(5b)#

Explanation:

If you are multiplying two square roots, you can combine them:

#sqrta xx sqrtb = sqrt(ab)#

#sqrt(2ab^2) xx sqrt(10a^5b) = sqrt(20a^6b^3)#

Write the expression as products of factors, using squares where possible:

#sqrt(20a^6b^3) = sqrt(color(red)(4)xx 5 xxcolor(red)(a^6) xx color(red)(b^2) xx b)#

Find the square roots where possible:

#=color(red)(2a^3b)sqrt(5b)#
