This is standard form (9x10 to the power of -4) to the power of 2
BARSIC [14]

Answer:

9×10 to the power of -8

Step-by-step explanation:

Cause when we add power to the power we multiply them

For example (2^{2} )^2 , we multiply the power so , 2×2= 4 so (2^{2} )^2 = 2^{4}=16

Same here ((9*10)^{-4} )^2 we multiply the powers so -4×2=-8

So ((9*10)^{-4} )^2 =(9*10)^{-8} = 2.323×10^{-16}
