Question

Heelp √2.8 x √4.2 / √0.24

Answer 1

√2.8×√4.2/√0.24 = √49 = 7

Answer 2

To evaluate the expression, let's first simplify each square root and then perform the multiplication and division.

√2.8 = √(2.8) ≈ 1.673320053

√4.2 = √(4.2) ≈ 2.049390153

√0.24 = √(0.24) ≈ 0.489897949

Now, we can substitute these values back into the expression:

√2.8 x √4.2 / √0.24 ≈ 1.673320053 x 2.049390153 / 0.489897949

Next, perform the multiplication:

≈ 3.433196972 / 0.489897949

Finally, perform the division:

≈ 7.005263157

So, the approximate value of √2.8 x √4.2 / √0.24 is 7.005.
