Question

21x(2a-3b)100a(13m+24n-6h)раскрой скобки

Answer 1

Ответ:

первый пример мы решаем так

21•2а-21•3b=42a-63b

второй вот так

100a•13m+100a•24n-100a•6h=1300a•m+2400a•n-600a•h

вот

Answer 2

To expand the expression and remove the brackets, you can use the distributive property of multiplication over addition. Let's go through the steps:

1. Distribute 21 to the terms inside the first set of parentheses: 21 * 2a = 42a 21 * (-3b) = -63b

   The expression becomes: 42a - 63b * 100a(13m + 24n - 6h)

2. Distribute 100a to the terms inside the second set of parentheses: 100a * 13m = 1300am 100a * 24n = 2400an 100a * (-6h) = -600ah

   The expression becomes: 42a - 63b * (1300am + 2400an - 600ah)

So the fully expanded expression after removing the brackets is: 42a - 63b * (1300am + 2400an - 600ah)
