When expressing small numbers in scientific notation, we use negative exponents for the base of 10. For example, 0.00002 = 2 x 10-5, where -5 is the negative exponent.

Answer 2

Answer:

(4000000)^3÷(0.00002)^4

(4×10^6)^3÷(2×10^-5)^4

(2^2×10^6)^3÷2^4×2^-20

2^6×10^18 ÷ 2^4× 2^-20

2^6×10^18 × 2^-4× 2^20

2^2×10^38

4×10^38
