What is the base in the expression 34?
The base is 3.
write 43 in expanded form
4x4x4=64
Check this 3(2 + 4y) = 6+12. What’s the error?
They forgot the y.
Solve ( 7(x + 4) )
7x+28
Evaluate ( 22 + (3 x 5) - 1 ).

What do you pretend when there is a letter and no number in a distribute property problem?
You pretend that there is a 1 in front of the letter.
Evaluate ( 33 + 22 ).
( 27 + 4 = 31 )
Find the mistake. They Simplified this equation as:
8 - 23 + 1
8 - 33
They didn't follow PEMDAS or combined terms that aren't alike
