Ten to the eighth is100,000,000 so just move the decimal on the 8.343 over 8 places.
834,300,000
When multiplying two terms with the same base, you add the exponents. In this case, x to the fifth power times x to the third power would be x to the power of 5 + 3, which simplifies to x to the power of 8. So, x to the fifth power times x to the third power equals x to the eighth power.

One third times nine to the eighth power equals 14,348,907
To multiply the two numbers in scientific notation, you multiply the coefficients (7.3 and 2.4) and add the exponents (8 and 3). Calculating the coefficients: (7.3 \times 2.4 = 17.52). Adding the exponents: (8 + 3 = 11). Thus, the result is (17.52 \times 10^{11}), which can also be expressed in proper scientific notation as (1.752 \times 10^{12}).
1 times 10 to the eighth power is simply 10 to the eighth power, which equals 100,000,000. This represents the number 1 followed by eight zeros.
9.452 times 10 to the negative eighth power in standard notation is written as: 0.00000009452
208.44
378,000,000
93 times 95 is 98 (add the exponents) = 43046721
The expression (2 \times 3 \times 3 \times 3 \times 5) can be rewritten using exponents as (2^1 \times 3^3 \times 5^1). This indicates that 2 is raised to the power of 1, 3 is raised to the power of 3, and 5 is raised to the power of 1.
13 to the power of 3 = 2197
y2 * y-5 = y2 / y5 = 1/y3
