The usual online notation for exponents is ^
5^4 * 5^-6 = 5^-2 = 1/5^2

all those words are just irritating

01.01 Nope. √81 = 9

01.02 ??
37^2 * 30 = 41070
(37)2 * 30 = 37*2*30 = 2220
Now sure how you get 314. Maybe your notation is obscuring the problem.
Answered by Waffles
The 314 is 3 and the exponent is 14
