Complete the identity.
cos 3x - cos 10x
cos *x + cos 10

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

in my opinion , its hazel

6-3=3

3*3=9

9+12=21

21/3=7

7*8=56

56 is your answer
