Question 59228
I am assuming the V means square root

{{{ x^2y^3 / sqrt(x^2 + y^2) }}}
x = 6
y = -8
Plug them in
{{{ 6^2(-8^3) / sqrt(6^2 + -8^2) }}}
work the exponents
{{{ 36(-512)/ sqrt(36 + 64) }}}
multiply and add
{{{ 18432/ sqrt(100) }}}
remeber a sqrt yeilds a + and a - answer
{{{ 18432/10 }}} and {{{ 18432/-10 }}}
reduce
{{{ 1843.2 }}} and {{{ -1843.2 }}}
