if you take your time youll figure out its e=mc2
(watts equal) voltage times current (e x I ) 120 x 20 resistance times current squared (r x I squared) 6 ohms x20 squared voltage squared divided by resistance (E squared divided by resistance) 120squared divided by 6 check OHMS LAW,
Yes, x times x equals x squared.
16 to the 4th power, or 16 x 16 x 16 x 16 = 65,536
If you mean ex squared, the answer is e2x
No. Cos squared x is not the same as cos x squared. Cos squared x means cos (x) times cos (x) Cos x squared means cos (x squared)
yes
x squared means x times x. Since x can be any number, x times x can also be any number.
x cubed
x cubed, or x³
x2 + 8x2 = 9x2
x times the sum of x and 9 x times (x times 9) x(9x) 9 times x[squared] 9x[squared]
