Since they both have the same base, simply add the two exponents.
17 + (-16) = 1.
so this is equal to 11 raised to the power or 1, or just 11.
11 raised to the 9th power divided by 9 raised to the 90th power
11^4 (11 to the power of 4)=14,641ANSWER: 14,641
2 + 3 + 3 x 11 = 38
2/5 x 11 is 4 2/5 or 4.4
2•2•5•3•7•11=4,620 
1... Anything raised to the power zero is one.
A negative power means the reciprocal of the number to the equivalent positive power. So 11⁻³ = 1/11³ = 1/1331 = 0.0007513 (4sf)
125
-6.285714286x10^11
no, the answer is : 2 ^ -5 = 0.3125
6561 and a power of -8 = 6553
