Answer:
The answer is 1st point.
Step-by-step explanation:
You can seperate everything out and multiply together :
(5xy²z³)^2/5
= (5^2/5) × (x^2/5) × (y²^2/5) × (z³^2/5)
= (⁵√25) × (⁵√x²) × (⁵√y⁴) × (⁵√z⁶)
= ⁵√(25x²y⁴z⁶)
The answer is 16,300. To get the answer, you just move the decimal over 4 places to the right and add your zeros in.
hopefully this helps
Answer:
Cheryl is correct.
Step-by-step explanation:
Cheryl solved a problem : 84 ÷ 0.01 = 8,400.
This is absolutely right.
When we divide any whole number with the divisor having decimal, we change the divisor to a whole number before performing the division.
To do this, we multiply both the numbers (divisor and dividend) by the same power of 10, until the divisor is a whole number.
= 
to make divisor a whole number we will again multiply both the numbers by 10.
=
= 8,400
Now answer would be 8400.
Therefore, Cheryl is correct.
