Any time you come across this kind of question were it ask us to solve for X but our X is power always make the base equal so that you can equate the power and solve for X.

You do know though that everytime you square an unknown you lose a solution? This also the same reason why we don't "cancel out " unknowns. the solution we lose from squatng the unknown is -1/9 . if we let y = x^0.5 instead, we solve this as a quadratic equation without losing the solution. Forgive me I'm a purist I mean no harm.

Very nice but it would have been best if he had verified the answer 1/9 because the square root of an exponent is a little unusual. v1/9 = 1/3 2^1/3 = (2^3)^1/9 2^1/3 = 2^3/9 2^1/3 = 2^1/3

An alternate solution for final answer once you have X = 9 * (X ^ 2) X / 9 = X ^ 2 (X / 9) / X = (X ^ 2)/X divide both sides by X 1/9 = X X = 0 second value assumed by inspection

Before watching: First and foremost, x=0 gives us 2^0=8^0 -> 1=1, so x=0 is a solution. Are there others? Well, 8 =2^3, so the right hand side can be written as 2^(3x). We now have the same base raised to two different powers equal to one another; this can only work if the powers are equal. Thus we have Sqrt x = 3x. Square both sides... X = 9x^2 Divide each side by 9x to get... 1/9 = x Our solutions thus, are x=0 and x=1/9.

Since we want to find the value of x, you need to square both side so that x remains itself on the left side of an equation.

@user-zr7zu2zo9u

@@justgaming9890 Yes 2³=8. To find the value of x you need to make bases to be the same. On the left hand side the base is 2 and on the right hand side the base is 8. 8 is the same as 2³=8. Therefore in the equation where there is 8 you replace with 2³ in older for bases to be the same.
