The answer is 3.0×10¹².

(5×10⁷)(6×10⁴)
(5×6)(10⁷×10⁴)
30×10⁷⁺⁴
30×10¹¹

Since the constant cannot be greater than 10, move the decimal point to the left.
30×10¹¹
3.0×10¹¹

The decimal was moved by one space, so the constant must be multiplied by 10 the one power. The 10 to the eleventh power still needs to be multiplied as well.

3.0×10¹⁺¹¹
3.0×10¹²

Since two exponents with the same base are being multiplied, it can be simplified by adding the exponents. Therefore, the final answer is 3.0×10¹².

What’s the best way to revise for maths? can never remember how to do anything.
Allisa [31]

Repetition is a guaranteed way to learn something. If it is a formula you need to learn, try doing flashcards and reading it over and over again until you can spell it without the flahcard. If it is something like factoring, just do a bunch of factoring problems until you get the feel of it.

Hello from MrBillDoesMath!

Answer:

-9 sqrt(5)


Discussion:

-2 sqrt(20) -  sqrt(125) =

-2 *2 sqrt(5) - sqrt(125)=                                as 20 = 4* 5

-4sqrt(5)- 5 sqrt(5)  =                                      as 125 = 25 *5

(-4 -5) sqrt(5) =

-9 sqrt(5)


Thank you,

A fair coin is tossed and a die is rolled. what is the probblloy of the coin being tails and the die landing on a 2
ZanzabumX [31]
The probility of getting a tail is 1 (tail) to 2 total possibilities which will be 1/2. The probility for rolling a "2" is 1 to a total possibility of 6 so the probability of 1/6. Since these are independent events and you want both to happen, you need to multiply the two results which will be 1/2 * 1/6 which equals 1/12.
