Question

if√2= 1.414,findthe value of √18+2√32-3√128+4√50

Answer 1

=√18+2√32-3√128+4+√50
=3√2+2+4√2-8√2+4+5√2
=12√2-8√2+6
=4*1.414+6
=5.656+6
=11.656

Answer 2

$\sqrt{18} + 2 \times \sqrt{32} - 3 \times \sqrt{128} + 4 \div \sqrt{50}$
=4.24+2x5. 65-3x11. 31+4x7. 07
=4.24+11.30-33.93+28.28
=15.54-33.93+28.28
=15.54-5.65
=9.89
