Answer:
Joni's mistake was to multiply the exponents instead of adding the exponents.
Step-by-step explanation:
we know that
When multiplying two powers that have the same base, you can add the exponents
so
-40-20=4x-20 _ -40-20+20=4x _ x=-10
The probability is 20%, or 1/5
14 / 1/3

1L=10DL
10L=100DL
100DL÷6DL=16.67
