Das is difference of 2 perfect squares
remember
a^2-b^2=(a-b)(a+b)
so
25x^4=(5x^2)^2
16y^2=(4y^2)
(5x^2)^2-(4y)^2=(5x^2-4y)(5x+4y)
cannot be factored further
Answer:
Options A and B
i.e., A. 4(3
) and B. 
Step-by-step explanation:
Like radicals are similar to like terms.
For example,
x, 2x, -10x,
, 7.3x are like terms.
are some more examples of like terms.
Similarly, like radicals are:
etc.
Hence, from the given options, like radicals to
are:
A.
and B. 
Answer:
10/4 equals 2 1/2 when simplified.
Step-by-step explanation:
