6x6x6x6x6 = 6 to the power of 5
So 6 to the power of 5 means 6 multiplied by itself 5 times.
2 to the power of 7 = 2x2x2x2x2x2x2 = 128
7 to the power of 2 (7 squared) = 7x7=49
3 to the power of 1 = 3 because anything to the power of 1 is just itself
Also 1 to the power of any number is always just 1 ( 1x1x1x1=1)
Square root of 49=
What number times by itself gives 49?
7 because 7x7 = 49
7a + 3
Like terms have exactly the same letters e.g a-terms or b-terms or no letters at all if they are number only terms.

Multiplying out brackets
The thing outside the brackets multiplies each separate term inside the brackets When letters are multiplied together they are just written next to each other ( pxq= pq) 5(2a+3)= 10a+15 3(4y+b-2)= 12y+3b-6 2t(5r-6w) = 10r-12w P(1+4q-2r) =p+4pq-2rp
