Question

What is the value of Fraction 1 over 2x3 + 3.4y when x = 3 and y = 4?

Answer 1

Answer:

I'm assuming the expression is (1/2)*x^3+4*y

If so, then,

(1/2)*x^3+3.4*y

(1/2)*3^3+3.4*4

(1/2)*27+3.4*4

13.5+13.6

27.1

So the final answer is 27.1

Answer 2

Answer:

=> 1/(2x³ + 3.4y)

=> 1/(2x³ + 12y)

taking values x = 3 and y = 4

so, 1/(2×3³ + 12×4)

=> 1/(54 + 48)

=> 1/102
