Question

Write an expression that is equivalent to 8 using each of the following numbers and symbols once in the expression.

Answer 1

optionsWe want to obtain an expression equivalent to 8 using these symbols and numbers.

The option that exactly matches this is,

`(7\text{ }(.)/(.)7)^2+7`

That is because,

7 divided by 7 is 1.

1 squared is still one, and;

1 added to 7 is 8.

So one answer is option D.

We also have another answer.

Which is;

`(7+7^2)(.)/(.)7`

That's because 7 squared is 49, and 7 + 49 is 56.

56 divided by 7 is 8.

So our answers are option C and option D
