Put on your table please:

book + notebook

calculator

laptop

pencil case

Here we go!

5a​2​​+7a​2​​=

1. 12a​4​​
2. 12a⋅a
3. 12a​2​​
4. 35a​2​​

Work out the brackets

(p−7)​2​​=

1. p​2​​−14p−49
2. p​2​​−14p+49
3. p​2​​+49
4. p​2​​+14p−49

And now, by your self!
(Typ in the answer,
without spaces)

​b​​3ab​​+5a=

And how does it work with plus and minus?

x​2​​+x​3​​=

3x​6​​+5x​6​​=

(x+2)(x−6)=

1. x​2​​−6x+2x−12
2. x​2​​−12−4x
3. x​2​​−8x−12
4. x​2​​−4x−12

(2a)​4​​=

(5a​3​​b​6​​)​2​​=

Simplify:

(5a​4​​b​7​​)​3​​=

1. Wait?!? What?!?
2. 15a​7​​b​10​​
3. 125a​7​​b​10​​
4. 125a​12​​b​21​​

Work out the brackets.
(Just typ in the answer,
without spaces. x squared = x^2)

(3x​4​​)​5​​=

Division with powers

​x​4​​​​12x​6​​​​=

Final question!
Typ in the answer, without spaces
a squared = a^2

​2a​4​​​​10a​20​​​​=

This is how I feel now...
