It is not possible to answer the question because there are too many ambiguities. You will need to resubmit it using parentheses (brackets).
For example, the first term could be (-3/5n)7 or -3/(5n)7.
3q over r to the fourth power
C squared times the square root of 5cd over 2 times d to the third power
1/2 times itself four times equals 0.0625
No, for example: (2^5x3^2)×5=1440 260x5=1300 (under 1440) 260x6=1560 (over 1440)
Cosine to the negative first power and cosine cancel each other out because cosine to the negative first power is one over cosine, and one over anything times anything is just one.

10/21 is its simplest form.
3q over r to the fourth power
The highest common factor of 9 and 21 is 3, so we divide both numbers by 3 to get 3/7.
5/x4
C squared times the square root of 5cd over 2 times d to the third power

2 over 5 6 over 15 8 over 20 4 times 10 to the hundtreth power over 10 times 10 to the hundreth power All of those are equivalent fractions of 0.4.
1/2 times itself four times equals 0.0625
