Answer:
Not sure exactly which equivalent expression you are looking for but my goal would be to write it without the negative exponent.

Step-by-step explanation:
They have the same exponent and it is multiplication.
There is a law of exponent that says
.
So we have
equals
.
Let's simplify (4*7)^(-2).
Since 4*7=28, we can say
.
Some people really hate that negative exponent. All that - in the exponent means is reciprocal. So
.
Answer:
She needs $30.
Step-by-step explanation:
170 minus 140 is 30.
First see how many times can 8 go into 52. So 8 goes 6 times, and it equals to; 48
Now subtract 48 from 52; 52-48= 4
Finally bring down the 0 next to the 4; 40
Now to get you final answer find out how many times can 8 go into 40; 5
Since it goes exactly 5 times then your final answer would be; 65
Hope this helps! :)
