what is the order of the numbers from least to greatest A=6.2x10-5 b =12.3x10-7 c=5.2x10^3 d=3.7x10-5
the answer choices is
a d<c<a<b
b B<D<A<C
C D<C<A<B
D B<A<C<D
Yes, the answer is B.
is it B??
To determine the order of the numbers from least to greatest, we need to compare the values of their exponents and coefficients.
First, let's rewrite the numbers in standard decimal notation to make it easier to compare them:
A = 6.2 × 10^(-5) = 0.000062
B = 12.3 × 10^(-7) = 0.00000123
C = 5.2 × 10^3 = 5200
D = 3.7 × 10^(-5) = 0.000037
Now, let's compare the numbers:
B < D < A < C
So, the correct order of the numbers from least to greatest is:
B < D < A < C
Therefore, option B "B<D<A<C" is the correct answer.
To determine the order of the numbers from least to greatest, we need to compare their values. However, these numbers are written in scientific notation, so we'll have to convert them into standard decimal notation before comparing.
Let's convert each number to decimal format:
A = 6.2x10^-5 = 0.000062 (move the decimal point 5 places to the left since the exponent is negative)
B = 12.3x10^-7 = 0.00000123 (move the decimal point 7 places to the left)
C = 5.2x10^3 = 5200 (move the decimal point 3 places to the right since the exponent is positive)
D = 3.7x10^-5 = 0.000037 (move the decimal point 5 places to the left)
Now, let's compare the decimal values of the numbers:
0.000037 (D) < 0.000062 (A) < 5200 (C) < 0.00000123 (B)
Thus, the correct order from least to greatest is:
D < A < C < B
Comparing this result with the answer choices, we can see that the correct answer is:
D) B < A < C < D
