Answer 2

Given,

A number squared decreased by ten.

To find,

Translate the given phrase into an algebraic expression.

Solution,

Firstly, let the number be 'n'.

Now, when it is said that a number is squared, it means that the number is raised to a power 2, or, the number is multiplied by the number itself.

Further, a number decreased by ten, means that we have to subtract 10 from the number.

Here, it is given that "the number squared decreased by 10". So, the given number squared will be

n²

Subtracting 10 from it will give us

n² - 10, which is the required expression.

Therefore, the given phrase translated into algebraic expression will be n² - 10.
