Question

Using a calculator, or otherwise,determine the value of(12.3)² - (0.246÷3) and write the answer

(i)exactly
(ii)correct to two significant figures ​

Answer 1

`\huge\text{Hey there!}`

`\huge\textbf{Assuming the equation is:}`

`\mathsf{(12.3)^2 - (0.246 / 3)}`

`\huge\textbf{If so, let's start simplifying it:}`

`\mathsf{(12.3)^2 - (0.246 / 3)}`

`\mathsf{= (12.3* 12.3) - (0.246 / 3)}`

`\mathsf{= (151.29) - (0.246 / 3)}`

`\mathsf{= 151.29 - 0.246 /3}`

`\mathsf{= 151.29 - 0.082}`

`\mathsf{= 151.208}`

`\huge\textbf{Therefore, your answer should be:}`

`\large\boxed{\mathsf{Exactly \rightarrow} \frak{\ 151.208\ } \& \textsf{ Corrected to two significant figures}\rightarrow \frak{150 \ or \ 151}}\large\checkmark`
