Please help me to resolve this.

If 5 exp 21 x 4 exp 11 = 2 x 10 exp n. Solve for n? exp is exponent of.

This may be an easy question but I am having difficulty resolving this. Thanks for your help.

5 exp 21 x 4 exp 11 = 2 x 10 exp n =
= 5exp21 * 2exp22 = 2*10expn =
= 5exp21 * 2exp21 = 10expn =
= 10exp21 = 10expn
thus, n=21
