Question

60(60+0,2)-60²=......................................

Answer 1

$60*(60+0.2)-60^2=60^2+60*0.2-60^2=60*0.2=6*2=12$
ответ: 12

Answer 2

Let's calculate the expression step by step:

60(60+0.2) - 60²

First, we simplify the parentheses by performing the addition:

60 + 0.2 = 60.2

Now the expression becomes:

60(60.2) - 60²

Next, we square the value 60:

60² = 60 * 60 = 3600

Substituting this back into the expression:

60(60.2) - 3600

Now we multiply 60 by 60.2:

60 * 60.2 = 3612

Finally, we subtract 3600 from 3612:

3612 - 3600 = 12

Therefore, the value of the expression 60(60+0.2) - 60² is 12.
