Answer 4

LOL :)

Answer 5

(x^a)^b=x^(ab)
x^a*x^b=x^(a+b)
x^a/x^b=x^(a-b)
x^-a=1/x^a)

Answer 6

\[\frac{5^{x-1} \times 5^{3x} }{5^{4x+1}}\]

Answer 7

is that it?

Answer 8

yes :)

Answer 9

ok base is same so add exponents in numerator and subtract the one in the denominator all the work is there

Answer 10

\[x-1+3x=4x-1\]
\[4x-1-(4x+1)=4x-1-4x-1=-2\]

Answer 11

and so your answer is
\[5^{-2}=\frac{1}{5^2}=\frac{1}{25}\]

Answer 12

hope steps are clear
