Question

If â2= 1.414, â3=1.732, then find 4/3â3-2â2 + 3/3â3+2â2

Answer 1

Answer:

2.063

Step-by-step explanation:

root2 = 1.414

root3 = 1.732

4/(3root3 - 2root2). + 3/(3root3 + 2root2)

= {4*((3root3 + 2root2)) + 3*((3root3 - 2root2)) }/{(3root3 - 2root2)*(3root3 - 2root2)}

=( 12root3 + 8 root2 + 9root3 - 6toot2)/(27-8)

= (21root3 + 2root2)/19

= (21*1.732 + 2*1.414)/19

= (36.372 + 2.828)/19

= 39.2/19

= 2.063
