Question

Multiply 4xy,5yz,9xz​

Answer 1

For the multiplication ; we need to multiply the terms as well as the variables .

The process is :

$\small{\longrightarrow{\sf{(4 \times 5 \times 9)}}}$

$\small{\longrightarrow{\sf{x \times y \times z \times x \times y \times z}}}$

Bringing the terms together :

$\small{\longrightarrow{\sf{180{x}^{2}{y}^{2}{z}^{2}}}}$

Supplementary information :

• If the terms to be multiplied are like terms we can directly multiply the constants and simply join the variables with them.

• If the terms are unlike ; we can separately multiply the constants and then add the variables.

• Note that the variables when multiplied add up the powers.
• Eg : y × y = y^2

Answer 2

Answer:

Given:

• 4xy , 5yz , 9xz.

Find:

• Multiply the given.

Calculations:

⇢ 4xy (5)yz (9)xz

⇢ 180 x² y² z²

⇢ x × y × y × z × x × z

That's,

⇢ 4 × 5 × 9

⇢ 180

Therefore, 180 x² y² z² is the required answer.
