I assume you're referring to 25.

Find the prime factorizations of the numbers under the cube root:

40=2^3\cdot5

625=5^4

320=2^6\cdot5

The cube roots share a common factor of \sqrt[3]5, so that

2\sqrt[3]{40}+3\sqrt[3]{625}+4\sqrt[3]{320}=2\sqrt[3]{2^3\cdot5}+3\sqrt[3]{5^4}+4\sqrt[3]{2^6\cdot5}

=\sqrt[3]5\left(2\sqrt[3]{2^3}+3\sqrt[3]{5^3}+4\sqrt[3]{2^6}\right)

We can simplify the cube roots now, since for any x we have \sqrt[3]{x^3}=x. So

=\sqrt[3]5\left(2\cdot2+3\cdot5+4\cdot2^2\right)

=\sqrt[3]5\left(4+15+16\right)

=35\sqrt[3]5
