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
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

When you multiply a number by itself, you get the "second power" of the number.That's also called the "square" of the number.Here are some examples:The second power of 5 is (5 x 5) = 25.The second power (square) of 10 is (10 x 10) = 100.The square (second power) of 6 is (6 x 6) = 36.The square of 3.1 is (3.1 x 3.1) = 9.61.
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

The number 2 to the 5th power is 32. To find the answer to a number to a power, you need to multiply that number by itself the number of times of the number in the power. For 2 to the 5th power you would multiply 2x2x2x2x2 (2x2=4x2=8x2=16x2=32).
5/50 = 1/10. You would multiply 10 by 5 to get 50 as the new denominator. To get the neumerator, you would also multiply 1 by 5 to get 5.
