Question

Find the value of each expression. Show your work (a) 1.42 (b) 300 - 2(0.5 +4.5)? (c) 3 2

Answer 1

As given by the question:

There are given the expression;

(a):

`\begin{gathered} 1.4^2=1.4*1.4 \\ =1.96 \end{gathered}`

Hence, the value of the expression is 1.96.

Now,

(b):

`\begin{gathered} 300/2(0.5+4.5)^2=300/2(5)^2 \\ =300/2(25) \\ =300/50 \\ =6 \end{gathered}`

Hence, the value of the given expression is 6.

(B):

`\begin{gathered} (1)/(3)/2\cdot((1)/(2))^3=(1)/(3)/2\cdot((1)/(8)) \\ =(1)/(3)/2\cdot((1)/(8)) \\ =(1)/(3)*(1)/(2)\cdot((1)/(8)) \\ =(1)/(48) \end{gathered}`

Hence, the value of the given expression is shown below:

`(1)/(48)`
