    I don't really get what you are asking



    If this is what you are asking (how do i multiply this??):
    (2)^2 . (25) = 4 x 25
    (5) (16) = 5 x 16




    What are you asking for the below? Is it a fraction or??????
    5 + 2
    3

    If you mean (2^2*25)/(5*16), then you should use that 25=5*5 and 16=4*4:

    (2^2*25)/(5*16)=(4*25)/(5*16)=(4*5*5)/(5*4*4)=5/4

    You can also do it like this:

    (2^2*25)/(5*16)=(4*25)/(5*16)=(4/16)*(25/5)=(1/4)*5=5/4

    If you mean (5+2)/3, then there's no way to simplify it further than to 7/3. Both 7 and 3 are prime numbers. There's no way to express them as a product of two smaller integers, like I did with 16 and 25 above.

    Hello,

    maybe you have to calculate a sum. Use the lcd(3,1)=3:

    \frac{5}{3}+2=\frac{5}{3}+\frac{6}{3}=\frac{11}{3}
