456*105 = 45 600 000, that is 456 followed by 5 zeros.
4-3 x 4-5 = 1.5265625 × 10-5
45.6 = 456/10 = 228/5
5 times 10 to the sixth power is expressed mathematically as 5 × 10^6. This equals 5,000,000. To calculate it, you multiply 5 by 1,000,000, which gives you the final result.
To evaluate the expression (4x10^4)(2x10^5), you first multiply the numbers 4 and 2 to get 8. Then, you multiply the powers of 10 by adding the exponents, which gives you 10^(4+5) = 10^9. Therefore, the final answer is 8x10^9.
There is no equation in that statement. There is only this 3 x 10^8. There has to be an equals sign, = , for there to be an equation. Please restate the term as an equality. Of course there is an equation: Answer = [3 times 10 to the eighth] to the fifth power

4-3 x 4-5 = 1.5265625 × 10-5
If you mean something like this: 54 then you multiply 5*5*5*5. The answer in this case would be 625. In any case with a number to a power, you multiply the number by itself however many times you have in the power. If it is just to the power of 2, you multiply it by itself twice. If it is to the power of 10, you multiply the number by itself 10 times. Most calculators (besides simple four-function calculators) have a button that allows you to input a number to a power and find the answer, which is much faster.

Use iterative adds. 5x2= 5+5 10x4= 10+10+10+10

To express (2 \times 10^5) in standard notation, you multiply 2 by 100,000 (which is (10^5)). This equals 200,000. Therefore, (2 \times 10^5) in standard notation is 200,000.
