Pooja writes the ratio x3=y4 to help her increase the size of a two-dimensional shape. If the new value of x is 15 units, what will be the value of y ?

Answer 1

To find the value of y, we need to solve the ratio equation x^3 = y^4 for y.

Taking the fourth root of both sides of the equation, we get:

y^4 = ∛(x^3)

y^4 = ∛(15^3)

y^4 = ∛(3375)

Taking the fourth root of both sides, we get:

y = ∛(∛(3375))

y ≈ 5

Therefore, the value of y is approximately 5 units.

Answer 2

That answer is wrong

Answer 3

My apologies for the error in my previous response. Let's solve the equation correctly.

Starting with the equation x^3 = y^4, we need to find the value of y when x = 15.

Substituting x = 15 into the equation, we get:

(15)^3 = y^4

225 * 15 = y^4

3375 = y^4

To find the fourth root of 3375, we can take the square root of the square root of 3375, which is √(√3375).

Using a calculator, we find that √(√3375) is approximately 7.15.

Therefore, the value of y is approximately 7.15 units.
