Easy and Basic algebra i need help with Please!!

^ is for square root.

1. solve for d b = L/4?d^2

2. solve for R 4?R^2oT^4



1. 6.75 X 10^6 + 3.13 X 10^4 =

2. 3.83 X 10^5 - 8.11 X 10^3 =

3. (4.16 X 10^4) x (6.48 X 10^2) =

4. (2.98 X 10^9) / (4.14 X 10^3) =

5. (7.64 X 106) x (6.45 X 10^-3) =

6. (4.69 X 10^-5) / (2.78 X 10^-4) =

just an answer check would it be

d = ?Lb/4?

and

R = ?L/4?oT^4

Thanks.

just an answer check would it be

d = ?Lb/4? ----> The b is in the denomenator : d = ?L/2?(?b)

and

R = ?L/4?oT^4

Thanks.

----------------------------

1. 6.75 X 10^6 + 3.13 X 10^4 =

Common factor : [6.75 x 10^2 + 3.13 ]10^4
=[675+3.31}*10^4
= mmmmmmmmmmmm ?~?
