  • Substitute the values


\longrightarrow\sf \frac {128-1024}{1024-64}


\longrightarrow\sf \frac {-896}{960}


\longrightarrow\sf \frac {-14}{15}

Laws of exponents:-


\begin{gathered}\boxed{\begin{minipage}{5 cm}\bf{\dag}\:\:\underline{\text{Law of Exponents :}}\\\\\bigstar\:\:\sf(a^m)/(a^n) = a^(m - n)\\\\\bigstar\:\:\sf{(a^m)^n = a^(mn)}\\\\\bigstar\:\:\sf(a^m)(a^n) = a^(m + n)\\\\\bigstar\:\:\sf(1)/(a^n) = a^(-n)\\\\\bigstar\:\:\sf\sqrt[\sf n]{\sf a} = (a)^{(1)/(n)}\end{minipage}}\end{gathered}

Answer and Step-by-step explanation:

2 * 2 * 2 * 2 * 2 * 2 * 2 = 128

2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 = 1024

4 * 4 * 4 * 4 * 4 = 1024

8 * 8 = 64


(128 - 1024)/(1024 - 64)


(-896)/(960)

896 and 960 both have 64 in common.

896 divided by 64 equals 14.

960 divided by 64 equals 15.


-(14)/(15) is the answer.
