Question

find the product of -8y³z × 4/9xyz³ × -27/5x³y³ and verify the result when x = 1, y = -1 and z = 2​

Answer 1

Answer:

Step-by-step explanation:

( - 8y³z ) × ( 4/9xyz³ ) × ( - 27/5x³y³ )

= ( -8) × ( 4/9) × ( - 27 / 5) × ( y³z ) × ( xyz³ ) × ( x³y³)

= ( 864 / 45 ) × ( x × x³ ) × ( y³ × y × y³ ) × ( z × z³ ) ( ∵ - × - = + )

= ( 864 / 45 ) × ( x⁴ ) × ( y⁷ ) × ( z⁴ ) ( ∵Bases are equal then powers should be add )

= (864 / 45 ) x⁴y⁷z⁴ is the answer.
