Question

Simplify

Answer 1

if the bases are same u can add the exponents. As u can see the base is x and it is similar to all three. Jst add the exponents while keeping the base same. Does that help? @selenamalter

Answer 2

\[-1-\frac{7}{8}+\frac{1}{8}\] is your exponent

Answer 3

um, ok,
7/8

Answer 4

no i don't think so

Answer 5

that is a \(-\frac{7}{8}\) in the exponent, right?

Answer 6

right

Answer 7

so your job is to compute \(-1-\frac{7}{8}+\frac{1}{8}\)
maybe easiest to first compute \(\frac{1}{8}-\frac{7}{8}=-\frac{6}{8}=-\frac{3}{4}\)

Answer 8

then finally compute \(-1-\frac{3}{4}\)

Answer 9

you get
\[-1-\frac{3}{4}=-\frac{4}{4}-\frac{3}{4}=-\frac{7}{4}\]

Answer 10

oh okay, so i think it would be B

Answer 11

no definitely not B

Answer 12

\[\large x^{-\frac{7}{4}}=\frac{1}{x^{\frac{7}{4}}}=\frac{1}{\sqrt[4]{x^7}}\]
