Question
I tryed to use ur method which is extended euclidean algorithm to figure out the valu eof "a" in (d), but it doesnt work. In ur answer of (b), a can be -165 based on this method, could u tell me is there any mistake in my calculation? thanks:)

Transcribed Image Text:d): 35a = 10 (45)
45 = 35x1+ lo
35=10x3 + 3
10 = 5x2 +0.
So
。 god (35₁43) = 5.
5 = 35 - 3×10 = 3§ - 3 × ( 45 - 35) = 4×351-3×45
However, 35× (-3) € 10 (mod 45)
