I think it’s 104,974
Because PEMDAS,
so first deal with exponents and 3 to the fourth power is 81. 6 to the fourth power is 1,296.
Next in PEMDAS is multiplication and division, so 1,296 times 81 is 104,976. Then 4 divided by 2 is 2.
Finally comes subtraction, 104,976 minus 2 = 104,974

Answer:

<h3>1/8</h3>

Step-by-step explanation:

Given the expression

\frac{(2^3)(2)^4}{2^{10}} \\

Using the following laws of indices;

\frac{a^m}{a^n}  = a^{m-n}\\a^m \times a^n = a^{m+n}

The expression becomes;

Step 1: Multiplication rule

=\frac{(2^3)(2)^4}{2^{10}} \\= \frac{2^{3+4}}{2^{10}}\\= \frac{2^7}{2^{10}}

Using the division rule of exponent (Quotient of powers);

= \frac{2^7}{2^{10}} \\= 2^{7-10}\\= 2^{-3}\\also \ a^{-m} = \frac{1}{a^m}\\ 2^{-3}=  \frac{1}{2^3}\\\frac{1}{2^3} = \frac{1}{8}

Hence the result of the expression is 1/8

Then multiply it to the 3rd power.


2nd answer is 1 / 1296
First add the expoinents
-12 +8 = -4

Then you would need to do the equation
6^-4 x 6^0
And this would equal 1/1296
