What is the value of 1/2 x three to the third power + 3.4y when x=3 and y = 4

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

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
