Which expressions are equal to 6^3•2^6/ 2^3
True [87]

Answer:

2^6 x 3^3 and 12^3

Step-by-step explanation:

First, solve

6^3 x 2^6/2^3

216 x 64/8

13824/8 = 1728

lets solve for the answers

6^3 = 216

Therefore, 6^3 is not an answer

2^6 x 3^3= 64 x 27 = 1728

because both expressions are equal to 1728, this is an answer. this answer can also eliminate 2^3 x 3^3 because it has a lower exponent than the answer that is equal to 1728. therefore, the value of it must be smaller than 1728

12^3 = 1728

This answer is correct, because both values are equal to each other, meaning that 12^6 is larger than 1728  

Therefore, your answers will be 2^6 x 3^3 and 12^3

How to solve this please help me 2/3×1/2(3/4÷1 2/5)​
Damm [24]

Answer:

0.624999999(repeating) so i would round it to 0.625 or 0.63 (both work and are rounded, its really up to wherever your teacher wants you to round it to if they want you to round it)

Step-by-step explanation:

2/3 x 1/2 (3/4 ÷ 2/5)=

simplify the parentheses (3/4 ÷ 2/5) to 1.875

2/3 x 1/2 x 1.875=

simplify 2/3 x 1/2 to 0.333333(repeating)

0.3333333333 x 1.875 = 0.6249999999(repeating)

round it to 0.625 or 0.63 (which ever one your teacher wants you to round it to)
