Answer:
where are the other statements
Step-by-step explanation:
A decimal would be 400.0 because it is exactly 400. a fraction could be a lot but an easy one would be 400 over 1 which, if you simplify would be 400. with no remainders.
A. 8^9/2= around 11585.2375; (sqrt8)^9= around 11585.2375. So choice A shows a pair of equivalent expressions.
B. (3sqrt125)^9=1,953,125; 125^9/3=1,953,125. So choice B also shows a pair of equivalent expressions.
C. 12^2/7= around 2.03394; (sqrt12)^7= around 5,985.96759. So choice C does not show a pair of equivalent expressions.
D. 4^1/5=around 1.31951; (sqrt4)^5=32. So choice D also doesn't show a pair of equivalent expressions.
Your answers are A and B.
I hope this helps ;)
7 1/5 = 7 + 1/5
= 7/1 + 1/5
= (7/1 * 5/5) + 1/5
= 35/5 + 1/5
= 36/5
= 36 ÷ 5
= 7.2
