Answer:
PEMDAS
Step-by-step explanation:
Use PEMDAS. Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction.
Start with your parenthesis, which is (9-6). This comes out to 3. Your equation should now look like 2+(3)x5/3
Then, go to your exponents. Since we don't have any, we skip this step.
Now, we look from left to right for any multiplication symbols or division symbols. Finding (3)x5, this comes out to 15. Now rewrite your equation, if should look like this: 2+15/3.
Repeat the last step and find your division symbol, and find this 15/3. That comes out to 5.
The last step is finding addition or subtraction symbols, and since there's only two numbers left we can just solve the problem from here.
2+5=7.
Answer:
a. 14 and 14= (-1)56+1(44)
b. 3 and 3= (-4)60+3(81)
Step-by-step explanation:
Case 1: GCD is the highest common divisor for both numbers without reminder
a. GCD of 56 and 42 = 14
b GCD of 81 and 60 = 3
Case 2: Express GCD as a Linear combination.
a. GCD = 14 which is also the difference between 56 and 42
Therefore
14= (-1)56+1(44) expresses 14 as a linear combination of 56 and 44.
b. GCD=3, we need to look for a multiple of 60 and 81 that their differences would be 3
Therefore the multiples are:
For 60 = 240 (60×4)
For 81 = 243 (81×3)
3= (-4)60+3(81) expresses 3 as a linear combination of 81 and 60
