Answer 2

QUESTION:

⧴ Multiply -5a²b² × 3ab

ANSWER:

we have,

$\mathbf{⤑ - 5 {a}^{2} {b}^{2} \times 3ab}$

Calculate the product

$\Bigg \downarrow\Bigg \downarrow\Bigg \downarrow \Bigg \downarrow$

$\mathbf{⟿ - </strong><strong>1</strong><strong>5</strong><strong> {a}^{2} {b}^{2} ab}$

we know that

$\mathbf{⤑ {a}^{m} \times {a}^{n} = {a}^{m + n} }$

$\Bigg \downarrow\Bigg \downarrow\Bigg \downarrow \Bigg \downarrow$

so,

$\mathbf{⟿ - </strong><strong>1</strong><strong>5</strong><strong> {a}^{2 + 1} {b}^{2 + 1} }$

now, add the powers

$\Bigg \downarrow\Bigg \downarrow\Bigg \downarrow \Bigg \downarrow$

$\mathbf{⟿ - </strong><strong>1</strong><strong>5</strong><strong> {a}^{3} {b}^{3} }$

Hence, solution is -15a³b³
