In the following math problem, which operation should you fo first? 8+3(7 x 4)- 5 ÷ 2 =

The operation you would do first is 7*4 as according to PEMDAS.

PEMDAS stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction.

In the order of PEMDAS, you would do whatever expression is in the parentheses, and in this case it is 7*4.

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
