The expression equivalent to 4^-5 • 3^-5 is 12^-5
<h3>What are equivalent expressions?</h3>
Equivalent expressions are simply known as expressions with the same solution but different arrangement.
Given the index expressions;
4^-5 • 3^-5
Using the exponent rule, the two values are have different bases but the same exponent and thus, we multiply the bases and leave the exponents the same way.
This can be written as;
4(3) ^ -5
expand the bracket
12^-5
Thus, the expression equivalent to 4^-5 • 3^-5 is 12^-5

Answer:
8.565
Step-by-step explanation:
Volume=4/3pir^3
3000m^3=4/3pir^3
3000/4/3=pir^3
25/pi=r^3
approx 78.539=r^3
r=4.2825
we know,
2r=d
d=2×4.2825
d=8.565
You can round the answer off yourself :3
Answer:
Your second answer, otherwise know as 1 in. : 4ft. is the answer.
Step-by-step explanation:
The new map is 3 times bigger than the old map, therefore your given scale for the first map will shrink by 3 to compensate for the new map being bigger. Divide 12ft by 3 and you get 4 ft., so your answer is 1in. : 4ft.
Answer: 94.80
Step-by-step explanation:
First, let's divide the salary she made from 5 hours of work by 5 in order to see how much she makes in a single hour.

Multiply this by 8 to find her amount made in 8 hours.
