Chapter 1, Problem 1.1P

To determine

To find:

The result for the given expression and verify the answer.

Answer to Problem 1.1P

Solution:

The required answer is verified.

Explanation of Solution

The given expression is,

1\2

-5^2

(-5)^2

10-6/2

5*4/2*3

The value of “1\2” is the reciprocal of $\frac{1}{2}$. Hence, the result is $2$.

Simplify the given expression -5^2.

$\begin{array}{l}-5^2\\ \Rightarrow -5\times 5\\ \Rightarrow -25\end{array}$

Simplify the given expression (-5)^2.

$\begin{array}{l}\left(-5\right)^2\\ \Rightarrow -5\times -5\\ \Rightarrow 25\end{array}$

Simplify the given expression using DMAS.

$\begin{array}{l}10-\frac{6}{2}\\ \Rightarrow 10-3\\ \Rightarrow 7\end{array}$

Simplify the given expression using DMAS.

$\begin{array}{l}5*4/2*3\\ \Rightarrow 5\times 4÷2\times 3\\ \Rightarrow 5\times 2\times 3\\ \Rightarrow 30\end{array}$
