Answer:
Step-by-step explanation:
Well 6 to the second power is when you multiply 6 x 6 = 36
And ab= -320
For 175 : 250 divide them both by 25 to get

<

25 goes into 175 > 7 times > 25 into 250 is 10 times! >

For the second one 16 : 40 just divide the top and bottom by 8 since 8 is a common factor of both which will give us

.
8 goes into 16, 2 times and 40, 5 times.
