​

Answer 1

Simplifying3a∗[8b÷4−6{a−(5a−

3b−2a

)}],

=3a[8b÷4−6{a−(5a−3b+2a)}]

=3a[8b÷4−6{a−7a+3b}]

=3a[2b+36a−18b]

=108a

Answer 2

Solution :-

➙ 3a [8b + 4 - 6{a - (5a - 36 - 2a)}]

➙ 3a [8b + 4 - 6{a - (3a - 36)}]

➙ 3a [8b + 4 - 6{a - 3a + 36}]

➙ 3a [8b + 4 - 6{-2a + 36}]

➙ 3a [8b + 4 + 12a - 216]

➙ 3a [8b + 220 + 12a]
