Do you mean $5\sqrt{60}.2\sqrt2$ ?

$5\sqrt{60}.2\sqrt2$

$5\sqrt{15\times4}.2\sqrt2$

$5\sqrt{15}\sqrt4.2\sqrt2$

$5\sqrt{15}(2).2\sqrt2$

$10\sqrt{15}.2\sqrt2$

$10\times2\sqrt{15\times2}$

$20\sqrt{30}$

Did that helped? :)

5^60 . 2^2

5√60 · 2√2

Or you could do it like this (if "^" = "√")

$5\sqrt {60} \cdot 2 \sqrt{2}$

$5 \cdot 2 \sqrt {60 \cdot 2}$

$10\sqrt {2 \cdot 2 \cdot 30}$

$20\sqrt {30}$

Whichever you think is easier to remember.
