I am sorry to ask again but please help ! I need help with this one. thank you whoever you are for helping me ! this is calculus problems that I have trouble solving. ​

Find the value of ax 4 ; a = 2, x = 1. select one: a. 2 b. 4 c. 1 d. 8

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares

Which expression do you get when you eliminate the negative exponents of 4a^2 b^216a^-3 b
