20 multiplied by 70 is 1400. See the attached image for the explanation.
The answer is 100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000. This is basically 101 zeros. The reason for that is because since 10^100 already has 100 zeros, multiplying it by one more will give it one more zero making it 101 zeros.
However, if you want it in an exponent form the answer is 10^101 I believe.

Answer:
Step-by-step explanation:
Givens
Let a = the first number
Let b = the second number
Equations
a + b = 39
b = 1/2 * a + 6
Put the second equation into the first one
a + 1/2 * a + 6 = 39 Simplify the left.
(3/2)a + 6 = 39 Subtract 6 from both sides
(3/2)a + 6 - 6 = 39 - 6 Combine
(3/2)a = 33 Multiply both sides by 2
3a = 33*2
3a = 66 Divide both sides by 3
3a/3 = 66/3
a = 22
b = 1/2 a + 6
a = 22
b = 1/2 * 22 + 6
b = 11 + 6
b = 17
Check
22 + 17 = 39
