    \[\sqrt[5]{x^4}\times \sqrt[5]{x^4}\]??

    first add up the exponents inside the radical (i.e. multiply) and get \[\sqrt[5]{x^8}\] but that is not the final answer

    10 /8 i add all the exponents

    since 5 goes in to 8 one time, with a remainder of 3, the final answer is \[x^1\sqrt[5]{x^3}\] or just \[x\sqrt[5]{x^3}\]

    you have it upside down dear, and the addition is not quite right \[\huge x^{\frac{4}{5}}\times x^{\frac{4}{5}}=x^{\frac{8}{5}}\] since \[\huge \frac{4}{5}+\frac{4}{5}=\frac{8}{5}=1\tfrac{3}{5}\]

    Find the solution of 5 times the square root of the quantity of x plus 7 equals negative 10, and determine if it is an extraneous solution. x = −3; extraneous x = −3; not extraneous x = 11; extraneous x = 11; not extraneous

    that may be a good explanation of why the answer is \[x\sqrt[5]{x^3}\]

    my friend got A and i think is C who's right ?

    it is certainly extraneous, i.e. there is no solution so why should you have to try and find it i have no idea

    i guess they want you to square both sides \[25(x+7)=100\]

    divide by 25 get \[x+7=4\] so \[x=-3\] really it is a bad question though

    Given the functions f(x) = −2x − 1 and g(x) = −3x + 4, which operation results in the smallest coefficient on the x term? Addition Subtraction Multiplication Two operations result in the same coefficient

    this is another one we are arguing about. she thinks its B i go with D

    add and get \(-5x+3\) subtract and get who knows because we don't know which one gets subtracted from which, but either way you will not get \(-5x\) you will get either \(-x\) or \(x\)

    if you multiply you get \[6 x^2-5 x-4\]

    so the answer is actually D, two operations result in the same coefficient, addition and multiplication
