Question

How to solve this equation? ​

Answer 1

Answer: 35× sqroot(2) ÷12 is the answer.

.

.

Explanation

Note that:

sqroot(2)= 1.414

1.414×1.414= 2

sqroot(8)= 2× sqroot(2) = 2×1.414

sqroot(9)= 3

sqroot(1)= 1

.

.

Answer= 2×1.414/3 - 1×3/1.414 + 5×3/(2×1.414)

Multiply and divide by 2 on middle term,

Answer= 2×1.414/3 - 6/(2×1.414) + 15/(2×1.414)

Add middle and third terms,

Answer= 2×1.414/3 + 9/(2×1.414)

Multiply and divide by 2×1.414 on first term,

Answer= 8/(6×1.414) + 9/(2×1.414)

Multiply and divide by 3 on second term,

Answer= 8/(6×1.414) + 27/(6×1.414)

Adding first and second terms,

Answer= (8+27)/ (6×1.414)

Answer= 35/ (6×1.414)

Multiply and divide by 1.414,

Answer= 35× 1.414/ (6×1.414×1.414)

Answer= 35× 1.414 /12 = 4.125

Answer= 35× sqroot(2) /12.
