Yoda,
Plz help me

Math 
Steve,
7^2 = 1/7^2 = 1/49
6^2 = 1/6^2 = 1/36
4^0 = 1 (as does any number n^0)
6^2 • 4^0 = 1/36 * 1 = 1/36
5^2 • 5^1 • 5^3 = 5^(21+3) = 5^4
(4×10^3)×(6×10^6) = 4×6×10^(3+6) = 24×10^9 = 2.4×10^10
1/10 • 4/10 = 1•4/(10•10) = 4/100 = 1/25 
Math 
Yoda,
Thank You so so so much :D

Math 
Steve,
My pleasure it is. :)
