Question

X is -4

f(x)= 5x^8-3x


The ^8 is the exponent for 5x!!!

Answer 1

327692

Explanation:

`65536 = (-4)^(8) \\ \\ 65536 * 5 = 327680 \\ \\ 327680 - 3(-4) = 327680 + 12 = 327692`

According to the Order of Operations [GEMS(A)\BOMDAS\PEMDAS etc.], in this case, you evaluate the exponent BEFORE multiplying. This is a common mistake people make.
