Answer:

What it is you are welding

Explanation:

If vertical welding, place above weld as a general rule.

Clean the metal you place the clamp on.

When connecting clamp, most machines work better when the cable is facing up unless stated otherwise.

Never ground on a stool in which you intend to sit.

Ground as close to the weld as possible.

Never put stinger on the ground clamp.

The sum of all the minterms of a boolean function of n variables is equal to 1.
Aleksandr-060686 [28]

The answers are as follows:

a) F(A, B, C) = A'B'C' + A'B'C + A'BC' + A'BC + AB'C' + AB'C + ABC' + ABC

= A'(B'C' + B'C + BC' + BC) + A((B'C' + B'C + BC' + BC)

= (A' + A)(B'C' + B'C + BC' + BC) = B'C' + B'C + BC' + BC

= B'(C' + C) + B(C' + C) = B' + B = 1


b) F(x1, x2, x3, ..., xn) = ∑mi has 2n/2 minterms with x1 and 2n/2 minterms

with x'1, which can be factored and removed as in (a). The remaining 2n1

product terms will have 2n-1/2 minterms with x2 and 2n-1/2 minterms

with x'2, which and be factored to remove x2 and x'2, continue this

process until the last term is left and xn + x'n = 1

Check the explanation

Explanation:
