Answer:
im doing the same thing and struggling so i need the answer also '\_($^$)_/'
Step-by-step explanation:
When you estimate, you round the decimal up.3.9 rounds up to 4 ,5.3 rounds up to 5.
4 times 5 equals 20.The actual answer is 20.67.
The simplified expression of (-5m⁷n⁰p⁵)(2m⁴n³p²)³ / -4m⁹n³p²y is 10m¹⁰n⁶p⁹ / y
<h3>How to simplify an expression?</h3>
The expression can be simplified as follows:
using indices law,
aˣ × aⁿ = aˣ⁺ⁿ
aˣ ÷ aⁿ = aˣ⁻ⁿ
Therefore,
(-5m⁷n⁰p⁵)(2m⁴n³p²)³ / -4m⁹n³p²y
Hence,
note
n⁰ = 1
(-5m⁷n⁰p⁵)(8m¹²n⁹p⁶) / -4m⁹n³p²y
Therefore,
-40m⁷⁺¹²n⁹p⁵⁺⁶ / -4m⁹n³p²y
Hence,
-40m¹⁹n⁹p¹¹ / -4m⁹n³p²y
10m¹⁹⁻⁹n⁹⁻³p¹¹⁻²y⁻¹
Hence,
10m¹⁰n⁶p⁹ / y
