Solve the system of equations using gaussian elimination method.
x + y + z - t = 4
2x - y +2z +3t = -8
-x + 2y - 3z + t = 4
3x + y + 2z - 3t = 9

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
