Which expression is equivalent to 4(6 + 8)?
10 + 12
10 + 8
24 + 32
24 + 8

First we'll need to do distributive property for that expression.
4(6+8) 
we would multiply the 4 by 6, and the 4 by 8.

so...

4x6=24
4x8=32

so the expression would be 24 + 32

Done! 

But if you're wondering my i put an addition sign in between 24 and 32, well that is because the question started with an addition sign, so therefor we would bring that down too.

Hope this helped!! :)

a - base

b - exponent

so,

the base is 8the exponent is 3the exponent tells you to multiply 8 together three timesthe expanded form is 8*8*8
