Question

Which is NOT equivalent to 64? A) 26 B) (24 )(4) C) (23 )(42 ) D) 43

Answer 1

Look at a factoring tree of 64 and see which does not work:

64 = (8)(8) = (4)(2)(4)(2) = (2)(2)(2)(2)(2)(2)

Therefore the only option which is not true is

23 × 42

Explanation:

Answer 2

only B is equivalent to 64

26 ≠ 64
24 x 4 is 64 = 64
23 x 42 is 966≠ 64
43≠64

hope this helps
