Question

3 plus (2 + 8) to the second power ÷4×(1/2) to the 4th power

Answer 1

$3+(2+8)^2\colon4\cdot(\frac{1}{2})^4$

We need to solve the expression above. To do that, the first step is to solve the operations inside the parenthesis:

$3+10^2\colon4\cdot\frac{1}{2^4}$

Then we need to calculate the powers.

$3+100\colon4\cdot\frac{1}{16}$

Now we need to calculate the division.

$3+25\cdot\frac{1}{16}$

We need to now perform the multiplications.

$3+\frac{25}{16}$

Finally we need to perform the sum.

$\begin{gathered} \frac{16\cdot3+25}{16} \\ \frac{48+25}{16}=\frac{73}{16} \end{gathered}$

The result of the expression is 73/16.
