Go by PEMDAS
Parentheses () There are none so move on
Exponents! ^x You have 10^6 is 1000000
Multiplication * You have 2.1 times your exponent... so you would take 100000 * 2.1 which is 2100000
D is division... you aint got none
A is adding nope... none here
S is subtracting and still... no subtraction so your final answer should be!!!.....
2100000! (hope it helps)
