Question

Q. If √2=1.414, find the value of
3√32 -4√50 +3√128 -7√18
​

Answer 1

Step-by-step explanation:

2√32 - 4√50 + 3√128 - 7√18 = ? if √2 = 1.414

simplified version of the above problem is

2√(16*2) - 4√(25*2) + 3√(64*2) - 7√(9*2)

=> 2*4√2 - 4*5√2 + 3*8√2 - 7*3√2

=> 8√2 - 20√2 + 24√2 - 21√2

=> - 9√2

=> - 9*1.414

=> - 12.726
