Question

Which expression means 56? A) 5 × 5 × 5 × 5 × 5 × 5 B) 6 × 6 × 6 × 6 × 6 × 6 × 6 C) 6 × 5 D) 5 6

Answer 1

if u mean 5^6, it is 5 x 5 x 5 x 5 x 5 x 5

Answer 2

It isn't going to be anything with a 5 as a factor (if it has something multiplied by 5) because all multiples of 5 end in either 5 or 0 so it isn't A or C.
It isn't B because that expression has 7 6s and 6×6×6=216 which is already larger than 56.
That only leaves D

Hope this helps :)
