Answer 1

[AI-generated answer — Bot GPT 3.5]

75–√ - 45–√ = √75 - √45

To simplify this further, we can simplify the square roots:

√75 = √(25*3) = 5√3

√45 = √(9*5) = 3√5

So, √75 - √45 = 5√3 - 3√5

Answer 2

To subtract the expression 75 - √45, we start by simplifying the square root term √45.

√45 can be simplified by factoring 45 into its prime factors:

√45 = √(3 * 3 * 5)

Since 3 appears twice as a factor, we can take one 3 out of the square root:

√45 = 3√5

Now we can substitute this simplified form back into the original expression:

75 - 3√5

The difference is:

75 - 3√5.

Answer 3

To subtract 75 - √45 - √, we need to simplify each square root individually before subtracting.

First, let's simplify the square root of 45. Since 45 can be factored into 9 * 5, we can rewrite the expression as √(9 * 5). The square root of 9 is 3, so we have 3√5.

Next, let's simplify √. The square root of √ is simply .

Now, we can subtract the two simplified expressions: 75 - 3√5 - .

Since 75 does not have any square roots, it remains as is. The simplified expression is 75 - 3√5 - .
