Well, darling, when you've got x to the fifth power and x to the third power, you simply add the exponents because you're multiplying those bad boys together. So, x to the fifth power times x to the third power is x to the eighth power. Easy peasy lemon squeezy!

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

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
