The standard form for 4.9x10^8 is 490,000,000. You can obtain his number by taking 4.9 and moving the decimal 8 spaces to the right since the 10^8 has a positive 8 number. If the 8 was a negative number, then you would move the decimal 8 spaces to the left.

$(x^{14}) ^{3}$ = $x^{42}$

Step-by-step explanation:

In this case in order to simplify we need to know what the "power rule of exponents" is. Simply speaking this rule states that when you raise a power to a power you multiply the exponents. So in our case we ill get the following

$(x^{14}) ^{3}$ = $x^{42}$

In order to get 42 we used the power rule which I mentioned earlier.
