Solve the following equation.

4.7 = 1.13x^2

Do i square root the 1.13x^2 first? or divide both sides by 1.13?

    Please excuse my dear aunt sally

    Both will work, but it is customary to divide both sides by 1.13, which avoids an extra square-root:

    4.7=1.13x²
    x²=4.7/1.13
    x=√(4.7/1.13)

    or

    √(4.7)=√(1.13)√(x²)
    x=√(4.7)/√(1.13)

    haha sorry. i didn't bother to read the entire thing. you must divide first in order to root both sides
