Question

I really need help with 1 and 2 please help me

Answer 1

For answer #1. just divide both numbers by 8.
Let's see:
400=8r
400/8=8r/8
400/8 equals 50
So, answer #1 is 50.

For answer #2, count the number of times it shows 5, then write that number on the top, in the right-hand corner.(or use an arrow to show it's going up)
Let's see:
5×5×5×5×5=5 times it shows 5
So, 5∧5 would be the answer.

Answer 2

r=50 because 8×50=400 so that is what r would equal
The exponent would be 5 the fifth power, because since the number your using to multiply it by is 5 and you are multiplying is by 5 fives it would be 5 to the fifth power
