Question

Which expressions are equivalent to 2^5•2^4? Check all that apply.

Answer 1

Answer:

2⁵×2⁴=2⁹

2⁵×2⁴=2×2×2×2×2×2×2×2×2

2⁵×2⁴=4⁵

2⁵×2⁴=8³×2

Answer 2

Answer:

[see below]

Step-by-step explanation:

Recall the product rule: $a^x+a^y=a^{x+y}$

$2^5 + 2^4 = 2^{5 + 4} = \boxed{2^9}$

Other expressions could be:

$2^{-2} *2^{11}=2^{-2+11} = \boxed{2^9}$

$(2*2*2*2*2)(2*2*2*2) = 2^5 + 2^4 = \boxed{2^9}$

Hope this helps.
