#1A is correct, but it is not scientific notation for the value.
#2B is also correct, but not S.N.
#3 is 0.593 x 10^4
But, to make it S.N., you need to have
5.93 x 10^3
#4 5.2 x 10^8 / 25 = 0.208 x 10^8
That is 2.08x10^7
Looks like you need some serious review on how to move the decimal point and change the exponents to end up with S.N.
thanks lun, rosey
lun and rosetta are right thank youuu
thanks a lot steve I got A 50%
roses is correct!!

1. To find the product of (5.1 x 10^3) x (3.2 x 10^3), you can multiply the numerical parts (5.1 x 3.2) and add the exponents of 10 (3 + 3).
So, (5.1 x 10^3) x (3.2 x 10^3) = (5.1 x 3.2) x 10^(3 + 3) = 16.32 x 10^6.
Therefore, the product is 16.32 x 10^6.
2. To find the product of (7.28 x 10^-2) x (9.1 x 10^-2), you can multiply the numerical parts (7.28 x 9.1) and add the exponents of 10 (-2 + -2).
So, (7.28 x 10^-2) x (9.1 x 10^-2) = (7.28 x 9.1) x 10^(-2 + -2) = 66.248 x 10^-4.
Therefore, the product is 66.248 x 10^-4.
3. To find the quotient of (2.965 x 10^7) / (5 x 10^3), you can divide the numerical parts (2.965 ÷ 5) and subtract the exponent of 10 (7 - 3).
So, (2.965 x 10^7) ÷ (5 x 10^3) = (2.965 ÷ 5) x 10^(7 - 3) = 0.593 x 10^4.
Therefore, the quotient is 5.93 x 10^5.
4. To find how much wheat Canada produced when the world production was 5.2 x 10^8 metric tons and Canada produced 1/25 of it, you can multiply the world production by 1/25.
So, 5.2 x 10^8 metric tons x (1/25) = 0.208 x 10^8 metric tons.
Therefore, Canada produced 2.08 x 10^7 metric tons of wheat.
The correct answer is B. 2.08 x 10^7.
