how did they get that big number 2209413024 from the matrix and also how did they get 1.027227817 x 10^10

(4/16)^t-6 2^a-tb

In the expansion of (4x -2/x)8 or (4x -2x^-1)8, find the following: a)the term containing x^6 b)the constant term (the term that does not contain x) I know a) is -262144x^6 and -4096/x^6 and b) is 286720 but i don't know how to do the formula of Tk+1 = C (n,k) a ^n-k x k

Solve 2^x ≡ 79 mod 101 when given 5^11 ≡ 79 mod 101.

It said to use the method of common bases

Combine Fermat’s Little Theorem with the Chinese Remainder Theorem to calculate the least residue of 3^1453 modulo 35.
