Question 162505
    what is the square root of 32 minus the cube root of 98?
.
{{{ sqrt(32) - sqrt(98) }}}
factor down to prime numbers:
{{{ sqrt(2*2*2*2*2) - sqrt(2*7*7) }}}
pulling out "pairs" from under the square root:
{{{ (2*2)sqrt(2) - 7sqrt(2) }}}
factoring out the sqrt(2):
{{{ 4sqrt(2) - 7sqrt(2) }}}
{{{ sqrt(2)(4-7) }}}
{{{ sqrt(2)(-3) }}}
{{{ -3sqrt(2) }}}
