Hello student, Please find the answer to your question below Given number is 4.19 X10 4 By multiplying 4.19 with 10 4 we get the standard form It can be written in standard form as 41900 So the...
Hello student, Please find the answer to your question below From(1): x^(1/2) = 7 - y , Letx (1/2) +y=11...........(1) x+y (1/2) =7..........(2) Squaring both sides: x = (7-y)^2 = y^2 - 14y + 49, Goto...
Hello student, Please find the answer to your question below Use identity a = e^(lna). i^i = e^[ln(i^i)] = e^[i*lni] Complex logaritm lnz = ln|z| + i*argz Then ln(i) = ln |i| + i*arg(i) = ln1 + i*pi/2...
Hii As you can see that the order is not given in which the variables are present in the summation series. Kindly provide those and then we will get back to you with the solution. . . .. .
the subset is {1, 2, 5, 6, 7,11, 12, 16, 17, 21, 22, 26, 27, 31, 32, 36, 37}
Be the first one to answer
Ans: Hello Student, Please find answer to your question below Final solution is x > 7/2, x < -7/2
