7x300=7x 3 hundres because in 300 hundreds there is 3 hundreds.I know that didnt make sense.so basically just look at the front number number its 3 so 3 hundreds but if your working with thousands and the front number is 5 its 5 thousands.I hope this was helpful.
So you would use GEMDAS or PEMDAS
-8-1+4x2
-8-1+8
-9+8
-1
Step-by-step explanation:
We need to find each of the following as a rational number in the form of p/q
(a) (3/7)² (b) (7/9)³ (c) (-2/3)⁴
Solution,
(a) (3/7)²

(b) (7/9)³

(c) (-2/3)⁴

Hence, this is the required solution.
A. 6 and b. 12. You take 3.6 and divide it by .6 then multiply by 2 for the second answer
